Together longer than most couples?

Stacey and I have been together since the late 80’s. We’ve celebrated many birthdays, anniversaries, good times and bad. We’ve even had passion and produced a child. But not together. You see Stacey has been coming to me for so many years that I’ve know her child that is now in college since before its inception. I even try taking credit for the birth by saying that I put the idea in her head to even have a child, or because of how beautiful I make her look that her husband couldn’t resist her. She of course denies it all, and especially denies my trying to take credit for her child’s life. She says, “if you want to take responsibility, you can pay their college tuition!” I’ve been there for the loss of her closest relatives. Listened to her fight with various people in her life and even sometimes with me! Every time our anniversary approaches she reminds me and says something like, “I like diamonds, and that we’ve been together longer than most marriages.” I have to agree being I’ve also seen many divorces in my years of doing hair. We know each other so well that we can talk pretty much about anything and we respect each others views and opinions. I look forward to every visit and story she has for me. I wonder how we should celebrate our next anniversary..?
