I don't think most of them to be fair look for petty arguments, the problem with the BB house is as near all previous housemates of past series say too, is that what seems petty to us on the outside becomes major to the housemates on the inside.

The people who often cause the petty problems to be blown up out of all proportion are the likes of the real backstabbers like Lydia and Deana when she was close to Lydia.

Things people may let pass or ignore on the outside are I would say far more difficult to overlook once trapped in the confines of the BB house.
So what we see as a petty argument to us, is far from petty to those who have to live in the house with the mix of housemates not of their choosing.
