Can people see an immediately cancelled friend request on Facebook?

[<3!]

I barley know this person, and their a mutual friend of me and someone. I was scrolling down the list and it happened, the request was sent. Awkward. So a clicked to cancel said request, and i REALLY need to know if they'll be able to see it now... Cause its like a really cute guy and that would be Super awkward...
What I mean is will he get a notification under the friend request thingie? 'Cause I'm pretty sure he only goes on like once a month, based on his profile lol

It usually doesn't happen immediately. Its been my experience that you will both see a few more posts then they will be gone. I'd say maybe in an hour. And the same seems to be the same when blocked

No, he won't know that.
