How many times have you been truly smitten by someone?

I’m just curious. I had the best time this week on a first date and can’t get my mind off of her. I’m nearly certain the feeling is mutual. I’m not saying “I’m in love,” but it is certainly a powerful feeling.This has not happened to me since maybe 9th grade when I was delusional. It is exciting, but also pretty darn annoying!

How many times have you felt smitten after only brief contact with someone?
