Yes on all three counts!
I've cried with Laughter during BB1 with Anna hilarious lady and with Brian BB2...
I cried with Happiness when Brian won BB2 and when Craig won BB1, actually I think I've cried most BB's with who's won!
I cried with Sadness when Emma was locked away and was crying alone. I cry a lot when other people are down on BB and feel alone! It's sometimes like watching a sad movie
Anyway
