To often we thought we were masters of disguising our addiction. In all honesty we were pretty terrible at it. I don't know if they know or not but I'm sensing that deep down you know that they do. There isn't much you can do about it. It's just one of those things that you just have to let go and see what happens with it. Maybe they talk about you, maybe they don't. There is no point getting upset over gossip.
