Quick assumptions and Masks

Ever had someone think a certain way to you, but you ended up being good friends with them. They stay by you through thick and thin but then a small event happens and you are left lost. You try finding yourself and it just feels like your wearing a mask so that no one can point you out. You can't find the right thing to do. Should you be like those people that change and change yourself so that you can still keep those friends. It just feels like like you are alone sometimes.
