My man!
Anger is simply a relfection of one's perception to a matter. We really cannot control how others behave to us, but we sure can control how we respond. In the end, it is all about mindset. It is however important that one makes their boundaries known, as this makes things a little better in the long run.
Good to see you here, man.
I feel we actually can, even if it's just a little bit, influence how people treat us. Not necessarily by anger, but by making our boundaries known.
