When this Friday's eviction takes place, it is likely that the housemate who goes will not be popular with the crowd.

I think boo-ing them is childish, nasty and immature.

If you want to be more childish, nastier and more immature, just remain totally silent. I've seen an unpopular speaker address a conference to total silence, and it gets the point across much better than boo-ing!!

Or I suppose you could all point and laugh.

I'll be watching on telly, anyway.
