They Grow Up To Fast!!

How can they grow up so fast! My 12 year old daughter recently began "dating" a sweet boy in her class. They sit together at lunch and talk on the phone a few times a week. Today their school celebrated Valentine's Day and she got off the bus beaming because he had given her a teddy bear, rose, and heart necklace for Valentine's Day. I can't believe how fast everything changes! Just last year she still thought having a boyfriend was silly and embarassing!
