1. It's the thought that counts.
When confronted with a person ready to "tally up points" during gift giving time, the thought only counts if it comes with the disconnected head of the person who gave you the homemade card and last minute chocolates. The idea behind "it's the thought that counts" is this: At least the giver thought of me. Unacceptable as most of us appreciate being a forethought, not an afterthought. And this is the only warning you're goimg to get since Valentine's Day is just a hop, skip and jump away.
2. Any friend of yours is a friend of mine.
Not only is this a bad cliche...it's pretty dangerous. I mean think about it...Charles Manson had friends too, right?
3. Can't judge a book by it's cover.
