She gets all nervous and talks over me why I try to get her to do certain things. Doesn't help 😉
Well, if it’s any help, my Father used to phone for help. He was an electronics engineer, but knew very little about computers. He would tell me what the problem was and ask for help. I would tell him to do something and immediately his confrontational and dominant nature would kick in and he would tell me I was wrong. There would be silence for a couple of minutes until he would say “So what do I do then?” And I would repeat my previous instruction. You can see how this plays out I’m sure 😂
