It is sad, especially it affects the kids when they see their friends are invited to a party and they are not. How long have you been living there? If it not too long do not worry about it. Also, try seeing people on play dates, strike up a conversation. Ask them about themselves (people love to talk about their family). Keep meeting people, I am sure one of them will hit it off with you. If it is a new place do not miss any neighborhood gatherings or an invited party. you can bake some cookie or something and take it to next door neighbor to say hi. invite them over to lunch or dinner or tea to get to know (this might work for not so immediate neighbors or even near by town acquaintances) . When then come home, initially have a plan to entertain them. it will help getting to know. it might take a few tries to find right people. Sometimes, the people you are mentioning in the post might already have a group of friends and they might not want include you in their circle. Ask them directly if there is a group that they hang out with. What kind of activities they do, if you like any of them, ask them if you can join them for that. If they say no, take it easy, if you get to go, you might find more friends there. America is a place where you dont et anything if you didnt ask.
