So she liked it, now do you think I should get out of the convoersation in a witty way:

She: Ha! Im right behind you on getting old older (wtf there is no old lady emoji)
Me: Lol I wouldn't be the guy who sends a old lady emoji. Just roll back your years on FB
sHE: Ill be 21 again soon!
Me: Green, sent her a math formula saying she would 28.
She: Lol!!! Im cracking up

So how would you respond to her bday wish? She said happy bday old man
