My ex wasn't blond, but he could have fit this description on many counts. The first one brought back memories about him getting frustrated because the only shampoo we had was "for oily hair" and he was upset because his hair was already greasy and he wanted it to be clean. I honestly couldn't explain to him that it's for washing hair that is oily and the result would be clean fresh hair. I could go on and on. The kids and I would just look at each other like does he really not get it?
My first husband was telling my kids at Thanksgiving a couple years ago that he needed a new computer but he couldn't get one because all of his passwords were stored on his current computer. I talked till I was blue in the face but he never ever got it. My son said quietly Mom let it go. I will get him a new computer and not tell him how I transferred all of his passwords but he trusts me.
