How to understand if a guy has bad intentions ?

You are overthinking this. He cared for your safety and he was being polite to your mom. To say nothing to your mom would have been rude, don’t you think? 

Two of my male coworkers told me I had nice legs but that was 30 and 25 years ago. I was flattered. Times have changed. Some men have not. 

Go with your instincts.

Maybe you are lesbian. Put it to the test, have a girlfriend show you a banana and see if you run screaming.

As a man, I see nothing wrong with this.  However, this is the reason I don't talk to women for a date.  Your thinking is the reason why I don't feel like I can ask a girl out on a date, without her thinking I'm "creepy" for liking something about her physically.

I am a nice, and honest man.  I smile because that's who I am.  And think about this.... what if you are in a relationship with a man you like for 10 years, then all of a sudden he tells you that you have nice legs.  You gonna break up over that???

Sorry but you might as well become a nun, and stay away from all guys, because they all think like this one guy does.  Sure, they don't come out and say it, but they think it just as much as the next one.

This is the way things are in the world of men, and guys liking you for different reasons.

Unless you are considering a relationship, does it  matter what his intentions are?

If he has a penis then he probably has bad intentions. 

how do you know he was waiting for YOU? plenty of people cough when they smoke. even my dad who smokes all the time.

sounds like you are cautious of people, which is good. but you shouldn't just assume the worst of them for silly reasons you have no proof.

let me ask you this, let's pretend he had NO ill intentions, and was just trying to be nice because he liked you. how SHOULD he have acted towards you? there are different types of people out there. some are shy introverts, and some are quite outspoken. some people who are shy occasionally try to break out of their shell.

he may have been staring at you because he wanted to build up the courage to ask you out. when you stopped smiling at him, he probably thought he should get you to warm up to him first by showing his kind side. the fact that he seemed creepy just shows how little practice he has doing this.

of course, this is all just possibility. the only way to know for sure is to do what you SHOULD be doing in the first place: talk to him.

try talking in front of other people if you are scared. that way there will be witnesses. i doubt he will do anything at work, even if he does have bad intentions. the more you get to know someone, the less you have to be afraid of.

we only fear what we do not know...

I do not necessarily think that he had bad intentions. What I think is that he genuinely likes you and was looking to form some sort of friendship with you. All those gestures, the small talk, staring and greeting your mom were his way of trying to connect with you and form a relationship. If you feel that you get on with this guy then I would consider giving him a chance and getting to know him. Ultimately, guys rely on getting little hints to guide them as to how you are feeling so that they know whether or not to continue talking to you or to back off. Therefore, when you see him, try making conversation with him by asking him questions that will get him to reveal his personality. You can also do things like compliment him and asking him to lunch. Both of those are great ways of letting a guy know that you enjoy his company. Finally, no one can force you into doing anything that you do not feel comfortable with. So please do not feel obligated to say or do anything around this guy. You are in control of this situation so be sure to not to do anything that you are not comfortable with. Good luck and I really hope this helps :)

You were minutes away from getting raped!
