Resolved Question

My kids have been wanting to play with the neighbors kids all week. Finally I call her and asked her if she would be outside in the afternoon so the kids can play. She tells me that she has to go to the store to purchase a small item and then she would be back and the kids can play. I was outside when I saw her leave and she again assured me that she would be back in a bit. So here I am waiting and waiting. An hour passes and then another hour passes and she still hasn't come back. First I thought maybe something happened so I started to wonder. Anyway, I end up going inside after but kept going to my window to see when she got back. She got back almost 4 hours later. Never called me to explain or apologize. People are either dumb or just plain inconsiderate. I felt bad for my kids who kept asking me where were they and why would they lie to us?
Just added: Do you think I should call and ask what happened? or learn for the next time.

Some people are just plain inconsiderate and don't think of others, they focus only on themselves. I would have thought she would have at least called or knocked on your door and said hey Im sorry this happened and we can't. Or sent of the the kids over (if they are old enough) to say my mom said we can't now.
Now you know how she is and you have to explain to your kids that she is just too busy to let her kids play.
Im guessing there are no other kids on the street or area?
