A little boy in preschool decided my girl was to be his girlfriend - he had his older sister write love notes for him and gave her the toys from his kids meals. It was kind of cute. By kindergarten, it was over and boys have gotten more disgusting ever since.
My son on the other hand had to be consoled several times in preschool - he'd be in tears 10 minutes into the drive home because some little girl who'd been his girlfriend all week had decided to be someone else's girlfriend. He'd sob the whole way to school the next day about how awful school was going to be without a girlfriend. Never failed that when I'd pick him up, he'd be all smiles and would have a new girlfriend. Now that we're in kindergarten, girls are just friends.
