it's completely normal to take part in gossip. in fact, it's a social skill. if you are afraid of what people say about you, then you are probably the problem here. i'm not going to go into why gossip isn't the worst thing in the world, but there are different levels of bad mouthing.

being late is also very normal. again, maybe it is you who are not being clear about your expectations or, more likely, are reading too much into it.
