Where did you learn to use analogies?

OK, I just heard one of the cruelest things I've heard in a really long time. I must be getting old and have been out of the game for too long.

When did we start teaching our kids to use analogies to let people down? Do they think this hurts less because they gave them a letter and an explanation?

My sister told me today, that her daughter (which is in junior high) received a letter from a friend explaining why she doesn't want to be friends with her anymore!
Here's part of the letter:

Dear Caitlyn,
Friendship is like a soccer game; right now you've been in the game too long, it's time for you to sit on the sidelines. It's time to bring my other friends in the game... but I still Love you.

Are you kidding me? When I was growing up, we just said, "I don't want to talk to you anymore or I don't like you anymore or just, Go home!"

I could be wrong; there could be something to this analogy thing! nah!
