When you're an actual legal, (not very) fully-functioning adult, but you're still begging your bestie for piggyback rides because you're still a mental child: *Jumps on Kat* Carry meee!!!
Kat: *Sigh* Fine.
Me: WHEEEEEEEE!!!!
Or then there's the 'just her carrying you in one arm while you giggle like an idiot' thing.
BECAUSE IF SHE'S THAT STRONG, DARN RIGHT IMMA DO IT!!!!!!
