Exactly my pet peeve!
Have you ever been annoyed, at one time or another, by someone in front of you who's walking and texting at the same time?
Urgh! Don't you wish you could shove that person out of your way?
This is especially frustrating when you are pressing for time.
As the video explains, it is plain inconsiderate and potentially dangerous!
Move to one side when you need to text so you do not delay the person walking behind you.
