I’m dating someone 8 years younger than me and the only way I think it works is that she likes me enough to learn all the references I make she doesn’t understand.
My wife is only 2ish years younger than me, and she already doesn’t get some references purely through upbringing. Only a couple things have been “before her time”
However, her best friend recently turned 24, married to someone who just hit 21. It feels like talking to children.
And since between the 2 of us we have 12 nieces and nephews under 15 and I speak to them whenever we’re visiting I feel like I can say with a little certainty, it reeeeally feels like talking to children sometimes.
