In my building, some people like to gossips.

You could also say "some people like gossip", but "to gossip" makes it clear that they are gossiping.

FAt first, their discussions are about the shape of the building, in a second time they involve people harshlybut after that, they talk harshly about other people.

You could also say "First, their discussions are about the shape of the building, but then they talk harshly about other people."

I figure outunderstand what's wrong with them and it's pretty sad, but I can't condoninge their behaviors anymore; therefore, when they tried to convince me about something, I tell them what I think about it, sugarcoating as wellmuch as possible.

"condoning" makes sense, but "condone" would be better.

When I feel my emotions taking over, I'll say a kind of, "are you done yet?".

It's understandable, but can be polished a bit.

Sometimes, it's better to keep away from some people, keeping your eyes and ears open.

Makes sense, just added a small adjustment.
