Can you get your GF to phone my wife and share her wisdom? You've got a keeper there!
Dear sir, I will call your attention to the specific phrase "GF". As we all know, when the GF transitions to "Wife", unexpected changes will happen. As an example, and which I'm sure you've no doubt experienced,
"Honey, I can't decide which one to buy"
GF is generous, kind, giving and loving and goes "get 'em all".
The wife who ... (no need for reasoning, she may be reading) will say "if you can't decide, you don't get any".
Unfortunately, OP will soon learn when the latest pair of PV's come out.
Congrats OP. Forgive us if our jealousy rears its head. For we are envious of your current position.
