One Direction find it impossible to stay mad at one another.
Louis said: ''We all actually find it difficult to stay annoyed with each other, which is a good thing. Like, if one of the guys did something to annoy me, and in my head I was thinking, 'Right, to prove a point to him, I'm going to really have to stay annoyed for so long.' I just can't do it.''
Louis believes friends shouldn't fall out over ''petty'' things as their bonds are not worth throwing away over trivial matters.
He said: ''I think life's too short. If you start a friendship and you're happy with it, what's the point of losing it over something that's probably petty.''
The 'Best Song Ever' singer also slammed celebrities who claim their fame makes it impossible to live a normal life.
He told Top of the Pops magazine: ''I've never understood people saying that they literally can't go out anywhere, because it's just not the case. You might have to stop and do a few photos, but then you carry on with what you're doing.
''The only time it gets crazy is when people know we're going to be in a specific place.''
His new album Underneath It All is out now.
