Clint/Audrey
Well. He wasn't really trying. Clint was bad at a lot of stuff, frankly including even wanting to get out of bed most days, but when he managed it all and did the thing, he was good at being social and charming in his own right. Not Tony Stark charming, but Hawkeye charming -- extroverted, but only in a part time capacity.
Still, he was glad he'd come.
"Do birthday hosting things. Demand stuff. Have more cake too," he said with a grin. "You do you. The only reason I don't stick around is if I break a hip."
So. Yeah. He'd be around later for hanging out. It'd be a good time.
