Laz is mean to everybody. If he's not mean to you, then either he doesn't like you or he is pissed off at you, or he doesn't even care that you exist. So, if he was mean to you then you should be happy that he acknowledges your existence and apparently approves.
Oh, wait; you were telling Laz that hobbes was mean to you. That's different. If hobbes was mean to you then that probably just means he didn't get any last night.
