I do that too - strange. Can have a "fave" movie on DVD which I dont watch for months, then get all excited when it comes on the telly. no logical reason to it.
The missus does this all the time, it drives me crazy.
You can watch About a Boy after the Snooker highlights, we're talking another 20 minutes here.
So we have a heated deabate about it, the snooker finishes, but she doesn't want to watch About a flippin Boy no more.
So I switch on the news. Passive aggressive doesn't bother me, it's a bit of peace innit.
