Hate that I have these moments and nowhere to share them ...

I was with my son today, on the way home from grocery shopping and he asked me if I would play with him when we get home. I told him I had to unload the groceries and quickly so we could go pick up his daddy from work. He sighed and said, "That sounds boring. I don't want to play alone. If my sister were here, I wouldn't be bored. I'd have someone to play with." Why is it that no one will ever understand? Wishing things were different and she were here. Thanks for letting me share ...
