And so it begins

When I got to daycare today Jack ignored me. I waved and he just turned around and kept playing with his friend. I turned toward the back corner of the backyard to find Dean. He was by himself on the treehouse. Suddenly, he climbed down and started running toward me. He flung himself into my arms and buried his face in my shoulder. He seemed upset. I asked him what was wrong. Well, he said, no one wants to play with me so I'm playing by myself.
Oh, that hurts. I didn't think I'd be dealing with this yet. Especially since he's a twin. I thought he'd be thrilled to get to play by himself! He went on to tell me that he wanted to tell B_____ something but she wasn't listening to him. I looked over at B_____ who was playing with her twin sister and another little girl. I tried to explain to him that sometimes the girls just want to play together and may not want to do what he's doing. He didn't care. He still felt slighted. Then he asked me to follow him all over the backyard to see this treehouse? And this one has curtains? And this has curtains, too? Look at this! You get the picture. Finally, I told him it was time to go but no, he wanted to show me one more thing. Off we go back to the treehouse where he was when I arrived. He showed me that he could climb up the ladder to get up to the treehouse but there's an opening in the "fence" that surrounds it and he could jump from there to the ground (it's only 4 feet high).
I gush about how impressed I am. He's so strong, etc. etc. He goes to E__ (one of the girls with B_____) and wants to know if she'll come with him to the treehouse so he can show her a trick. She just looks at him and walks towards B_____ and her twin sister. Dean turns to me, pride injured, and says accusingly, "See what I mean!". He stomps up the ladder to the treehouse and announces, "No on will play with me!".
I look at him and say, "I'm playing with you".
He looks at me and with a sheepish grin says, "Oh. Right."
