Potioncat:
I always thought, though there's nothing to confirm it in canon, that 
when the Muggleborn kids went home, the electronics would mess up. TV 
reception would be fuzzy, the microwave would burn things. That sort of 
thing.

Mrs. Granger would say, "I don't believe it! We had this microwave 
fixed after you went to school and now it's acting all funny again! Why 
can't they make things to last?"

But in the Snape household it would have been, "Yer rotten kid! Get 
away from the telly before you break it. Now you've made me miss the 
big play!"
