This movie is about a man who met a woman and they both exchanged numbers but they lost it but they keep thinking about each other and they keep going back to the place where they met but didn’t see each other, they even told their friends about it, I guess they meet again, I remember part of it where the woman went to dinner at a restaurant with her friend and took up a napkin and said “what if it’s this” and looked on it but it wasn’t it, it’s like the number was written on a napkin and she couldnt find it. I think it’s also a Christmas movie but I’m not sure
