Should I check out a strange noise outside my window?
I don't know if you should. Why are you so interested in that noise?
It reminds me of someone that I like
I don't think it's going to be worth putting yourself in that situation. I think it would be best to see if the noise just dies down.
Yeah, but what if it's someone that I want to see?
I doubt it's someone that you want to see. If it was someone that was trying to visit you I'm sure they would let you know via text or phone call that they were at your house.
