First off...I want to say this is my first post and I guess I'm looking for advice. First, I want to tell the story...sorry for the grammatical errors!
So, a few months ago...I took my grandfather to the emergency room. He was just having a bunch of congestion and sometimes his breathing would be a little rough. Nothing dire but he was a little worried. Anyways, while we were just sitting there waiting for results from some tests, I decided to go to the lobby to use the bathroom and get some water (I am a guy btw). I came to a double door that had no handle and right beside it was the huge desk area surrounded in glass. The girl, who was roughly the same age as I and very pretty said waived your hand over the black box and the doors will open. So I walk up to the door and there is a black box over the door...as I was reaching up...I realized...oh this is not the right box...so I quickly turn to the right box on the side of the wall. I wave and it opens but I look back at the girl and we started laughing because she totally saw me goof up. So I go get some water and come back. Later, the doctor had to use the room so I had to stand outside the room and wait. As I was waiting, the girl was walking in the hall and she passes me and we both made some sarcastic door jokes to each other while having huge smiles. As the night progresses, I'm sitting in the room and she comes in and starts talking to grandpa and my mother who was with me and she kept looking at me and cutting up with us but me in particular. The last time I saw her, I went back to the lobby to throw something away, and I stop at the double door, wave my hand over the box and the door opens (she's now sitting at the very opposite edge of the desk) and we both turn our heads and just give each other that huge smile. The kind of smile when you are into someone. I know you might think, oh she might have just been smiling at you...but I've been around a lot of girls. I have had a lot of interactions, and I know that body language she was giving me was definitely the "I'm into you" kind. Also, not to mention, my mother after we left was saying she thought that girl was way into me.
Now the dilemma. I thought in my head while I was there, I should just go and give her my number...but she's at work...in the ER...and there is multiple co-workers around...and I had a sick grandfather.....so I didn't. I know now, I should have. But she's been in my mind ever since and its been months but I don't want to be that creepy guy. I just want to have coffee with her and see if there was anything there. There's a good chance she might not remember me...but if she was at least feeling the moment like I was...maybe she does? Any advice how to reach out to her? I know the whole "let it go" scenario...because I'm literally doing that now but I thought about taking a chance?
