The bystander effect is really common. I remember when I got first aid training, they told us that in an emergency, you have to tell a specific person to do something rather than ask "someone call an ambulance".

I think bystander effect should be regularly discussed in schools so people will be aware of it. Getting people to automatically respond and do something and offer help is a pretty important step to making our society safer and healthier.

So you first said they try to do/offer to do something like walk you home, buy you something, etc. and you said you don't want that. Now here you say you want them to do something, in particular when they see something bad happening (i think you meant when they see girl treated poorly by a boy/man). That seems kind of confusing.
