What if Harry kept his parsletongue ability after the war?

Albus gets a snake one year as a pet because it's cool. And one day he just walks in on Harry and the snake having a deep conversation.

So when Albus is 17, he loses his virginity and the snake was in the room. So next school break, the snake is like: "OH MY GOSSSSSHHHHH YOU'LL NEVER GUESSSSS WHAT HAPPENED" and Albus is mortified.

But whatever happened, Ginny refused to let Harry name the snake. Because he'd probably name it Basilisk Nagini
