I've been wanting to put some things.
Here they are:

Please understand that...I DO have the right to reject you or to remove you from my friends.

Please understand that...I DO have the right to block you if I sense something that isn't good or correct from you.

Also, I DO have the right to not accept your trading offers, this includes PET TRADING too.

Woof, Finally, listed them all here.
Might add more later on...
