I don't play baby games.
How stupid. I am not a guard for anyone. If my friend has done something wrong, then my friend needs to address that. Not me.
If you pick on someone in front of me, you'd better realize that I am there and I will answer you no matter if the person you are picking on is my friend or not.
That is how I roll. No one needs to stand up for me and I don't need to stand up for anyone who should be standing on their own. That is the type of friends I admire.
