With three kids, all in their twenties, I must say that we have SEVERAL "exs" that we have remained friends with. I just love my kids' friends & those they have dated. They spend so much time at our house & you get so close to them, it's hard when they quit dating!
But, I think they all know they will always be welcome at our house anytime! Kassidy, the bride, cuts my sons hair!! When we lost Mocha last year - you would not believe how many of our kids' friends were as sad as we were, because Mocha had been around during their junior high & high school years!
