My Dad did that to me once. He lives in Scotland and I live in Indiana. He was sober too at the time.

But it was about 3 years ago that he flat out asked me why I hadn't transitioned yet. I was kind of stunned. he went on about how I needed a plan, start saving for it, etc. And I was just too dumbfounded to even respond. My mind was screaming 2 things.
1: Who the hell are you? and what have you done with my Dad?
2:He's actually been researching this?
After all the crap that parents seem to pull on their trans children for the majority of posts I had ever read, it was so extraordinary.
