Where's the worst place to text?

On a rooftop. Cause you're walking around with your eyes glued to your phone and probably sexting back and forth while completely oblivious to your surroundings and then you fall 10 stories.

While walking on a busy street on a sunny day.

In a car while driving.

LOL at the TDS for answers mentioning texting and driving. It is beyond idiotic to text while driving.

At a religious service

Around the rim of a volcano.

In class! Teachers will rip you apart!

inside the church will the mass is ongoing, during every dinner, on the street while walking, on the road while driving.

No place. It becomes worse when you text while someone is talking to you.

Detroit. People will jack that phone.

In the driver's seat
