How can you not love this little boy? I find myself wondering this most days. He's sweet, very loving, funny and loves to play just about any game.
He's also not shy, for which I am so thankful. (He inherited my aversion to sleep and most veggies, but not my shyness.)
And he wants friends to play with. When we first moved here, we were so excited to see all the play stuff in the backyards of the houses behind ours. So was Little Elvis.
Once the weather finally got warm enough, we were able to meet the families. Most of the children are older -- 6 and 5. The youngest is Little Elvis' age. She is shy and does her own thing.
The older kids were nice at first, but now they are mean to him. They exclude him, won't play with him, and the oldest will come to the fence and taunt him -- saying that he can't come over and play. 
I understand that he's a good bit older, so playing with a 3-year-old probably isn't that fun. But is it necessary to be so mean? Little Elvis will go to the fence when he sees them and ask if he can come over, and then cries when he's rebuffed and it breaks my heart. Cracks it wide open.
If we do go over (which I avoid as much as possible) they won't play with him, and run from him. He thinks it's a game, and doesn't usually notice their rebuffs.
This happens with my cousin's kids as well. They are older, 5 and 7, and the little boy is so mean. We didn't have a family birthday party for Little Elvis because I couldn't take him being so mean to Little Elvis on his birthday.
Hopefully it's just an age difference, and by the time he's old enough to understand what's going on, they'll be more inclusive.

Until then, we're going for walks to look for other buddies, and playgroups at the park. And Little Elvis is waiting for Baby Plum to get big enough to play.

I hope they'll be inseparable, but kind to other kids who don't have siblings or are younger.
