Oh, so funny. I tested at 3:45am the other day. Dh was leaving for work about 6:30 and I told him I got a pink line. He says "what does that mean?" (he's not functioning that well in the morning!). So that evening I said something related to the pgcy, I don't remember what, and he chuckled and said "Oh, I forgot all about that!". All day long and he never remembered! It's amazing how focused on one thing he can be.
Of course he hasn't forgotten since then
