What are we supposed to do when being sung happy birthday to?

Smile, sing along, stare at the cake, act all bashful I dunno cringe lol

Smile and say thank you, and blush if you need to. I know, it can be awkward.

Just sit there quietly with a pasted grin on your face, look at the cake to avoid eye contact with anyone and pretend you're enjoying it.

Sit and smile awkwardly!

You are the year 2019?

Do a line

Shout “this is my jam!” and wave your hands in the air like you just don’t care.

Put on a fake smile and blush while u scream in ur head 👍

Projectile vomiting would be fun.

Hahhaa I hate it. I stare at the cake!
