Yes I'm puerile, and old enough to know better . DD in Yr5 has been studying the solar system this term and I seem to relish any occasion when I can say: "DH look at Uranus, it's amazing" etc
DH says it was funny the first time but he still smirks.
DS13 thinks it's funny (he would) but DS11 thinks I'm "silly"
AIBU?
