If someone was following in the street or something, would you notice and what would you do?

Answer 1

I have had such a thing happen before, and ducked into the nearest convenience store, where it was well lit, and a phone available. You never want to allow a stranger to follow you home when you're getting an ill vibe. You can call a friend to pick you up, or call the cops, if need be.....

Answer 2

I stop and turn and face them. They do not like confrontation so either they stop and go somewhere else, or they walk past you. When they walk directly up to you, I tell them STOP! with my hand out, you do not need to get any closer to me. If they get even closer, I go into a aggressive posture, ready to attack. They get the message that I am not going to be an easy victim.

Answer 3

walk faster and try to lose them
