The only infantile element involved is the pitiful likes of "you'se". The wager's fully honorable and entirely legitimate. "You'se" sad sorts are simply too much the obvious jokes to ever be up for it, and you clearly know it, or you would have something more tangible to offer than just childish hissy fits in response. Tip: Work on trying to better at least even poorly impersonate a "pilot" princess...and I did note I'd even offer a "trophy" just for "participating", so I'd have thought your generation would be more comfortable with it than seems the case. Oh well. No matter really. "This is Sparta!" after all.
Per: "not your stunt flying"? Umm..."stunt flying"? Really? Sigh...OK, so you never progressed as a supposed "pilot" past at best stall recovery, one must assume? Be careful to never, never, ever exceed even 30 degrees of bank then sweetheart.
"Don't you ever get sick of yourself...?" Not so much as you would wish or even imagine. Life's bounty never fails to include individuals like yourself to laugh about. 😉
