Why Do Ex-Boyfriends Call Right Before the Holidays?

You know who they are ladies... ex boyfriends, old dates that never seemed to go anywhere, guys that might have had a thing for you but never really acted on it right away. Why is it that they all reach out to you about 2 weeks before the holidays - it is almost like clockwork. An alarm has gone off in their head and they think...who knows what they are thinking? At first you get a random text from a guy you used to date and you think... ok, that was strange but cool; you might even consider going for a drink to catch up. Then, a few hours later, another text but this time from a different old flame saying how he always thought there could be something. The second guy, we will call him Shawn, is a successful psychiatrist in his mid-40's and when I was interested in him about 2 years ago, he did not seem to have the time for me. He was more interested in his hot mess of a client, who was not a client but was a close family friend that he was doing some "alternative healing" with. It all sounded a little suspect to me. Finally when I moved on and lost interest in not seeing him ever or him telling me this odd story about this "client" who happened to also be a quasi-famous drama-queen, he seemed to want to revisit our possibility. He always said there was a connection. I felt something in the beginning but after that, was not so sure. So now, I am left with this question, why, in the same day are the two guys who I have not seen in over a year suddenly wanting to get together this coming week before the holidays? Are they lonely? Do they miss me? I guess they probably have their pick of girls to try to call and maybe they have called a few but for whatever reason, we do try to tie up those loose ends before the holidays and of course we want companionship. I, personally, would want to keep myself open to find what I really want OR be with someone who I know who makes me happy. I don't think I want to revisit tainted old relationships or possible relationships. I don't know if I'm being closed off, if I have already made my decision about them or I should give it a second shot. I think that if I was willing to give it a second shot, it would be after the holidays because in a time of parties and events, friends, ect, there is no reason to tie yourself to something you are unsure about. Right? Right.
