Puppy Love

So my 5 year old has got the hots for this other little 5 year old that lives down the road. It is really cute. Her name is Catherine and he talks about her all day long. This is his first crush. He's been showing her how to ride a bike and they give each other toys. The only annoying part is that he wants to be with her ALL day long. He'll even argue with me during meal times claiming he's not hungry so he can go over there and see her. The parent's have 1 year old twins and if I was them I wouldn't want to watch the neighbor boy all day long. I even offered to let the 5 year old come over here and play so they can get a bit of break. And he even sneaked out! Yup, cupids' arrow hit HARD. He will literally sneak out of the house to go over and see her even if we tell him he can't go over there right now. And when we ask him why he snuck out his response is "I just wanted to see her and you won't let me right now." I playfully asked him if she was his girlfriend and his face got bright as a tomato, he smiled, and shrugged and then shook his head yes. Ah, puppy love.
