What do you think about me wanting to help a random stranger out?
Have you helped strangers before?
No, only friends so far.
It is normal for people to help each other out. You should not let other people take advantage when you help them out.
I'm trying to be nice, it's hard for me to stop it.
You shouldn't ever want to stop being helpful. Not everyone out there cares about others, and it is great that you do.
