Do you think the avengers insist on celebrating every single one of Steves missed birthday? Kinda like if they need an excuse to relax and party they'd just throw one and pull out a cap cake stocked in the fridge
And can totally imagine though tony trying to find something to put the cake on becuase its so big and the shield is sitting there so he shrugs and throws it in the oven with the cake because "Its vibranium, right? Nothing can hurt it?
Stark almost lost that magnificent facial hair due to a small inferno.
Because that's the most concerning thing, Steve xD god.
