Sometimes it is hard to be single. Though I also know it can be hard to be a couple too. By not dating your Grandparent, I think you can find the goodness in whichever situation you find yourself. Example - "daaag I wish I had a boyfriend, oh well, things could be worse, I could be dating my Grandpa." Or "maaaan my significant other is annoying the stink outta me, oh well, things could be worse, i could be dating my Grandma and we could be paying a surrogate to have our child."
In case you're calling the hospital to have me committed, read this article first (then you can call).
