Sometimes that's not so cool if it catches you off guard.
I think Seinfeld did a show on this. It's the mandatory "invite" but with no real expectation for the invite to be accepted. Like when people say "we should do something" and nothing happens.
That would be hilarious. "Ok let's do it." "Wait, what? (in your head you're thinking I didnt think he was serious)"
Ps. Jay,forget about the pants, the jersey, your truck is bomb!!!!
