Yup! If you have family, you are furtunate. If not, you are probably single and if you are in your mid to late 50's, you really don't have any friends because those that you did have eventually married and created families and lives of their own. You eventually found you had nothing in common with them..........
It ain't easy being single that late in life......
Um, well, I'd agree with you that it's tough being single, particularly if you're trying to raise children. It can be very lonely. But if you are in your forties or fifties and "really don't have any friends", there's something wrong, and you should be examining yourself to see what it is. Sure, the old friends get married, but there are a lot of other divorced and never-married people in our cohort with whom we can make friends. You should make friends with people of both sexes and have fun with them.
