B.S.
Try not to compare your life to your parents growing up. Life for you can be different if your happy with it.
I know for myself my parents did not have a lot of friends we did much with, but we did do things with my dads family sometimes and sometimes with my dads cousins. But a lot of things we did on our own as a family. I remember my childhood being fun without "couple friends"
I think everyone needs friends and it sounds as though your not short on friends as your worried about doing things with other families. Just realize its not a necessity to a happy childhood. Who knows maybe when you stop looking a friendship will come along.
Good luck
