Challenge them.

Often they want to shut down all the lights on the street, so they are only with light.

For example you say:

You : I was successful today at x.

They : Thats nothing difficult, i did that x time lalala.

You : Why you are saying that? You are not happy with me? (change it to them)

Or tell them, well it is important for me and i wanted to share this with you because i care about you, you should try that as well.

Dont be scared, if they dont know about their behaviour challenge them so they learn. If they know it, challenge them again, because they diminish people which are okay with that. If you fight back they will understand.
