What is the obsession with teams?
 

Obviously some people gravitate towards one another and plot but most times they end up turning on one another at some point.

BB is a game, fake environment and most people are out for themselves!

You need allies to survive in the BB house so people always end up in teams

I like there being teams, divides and tensions. Of course they will end up turning on each other. They want that 100 grand cheque in the end. I enjoying seeing the war between two teams and the 1 or 2 bunny hopper housemates who jump from group to group.

This. Only a few housemates with few or no friends have survived a long time in BB. You need to arse lick a bit first really. Not sure how I would cope with up to 10 weeks with a few or no friends. Or.. I could just not care at all and piss most housemates off while I am in there. The public can get bored with the same people being up most weeks though and may not vote for the umpteenth time.
