Welp, I found an unexpected one. I had my iPod on shuffle and some Puerto Rican Christmas music came on and I lost it.
I think it's a mixture of things
1) I'm very home sick today for some reason. I mean, I do miss home, but it doesn't normally affect my mood
2) It's bittersweet--it reminds me of many post-Christmases through Three Kings Days I spent in PR as a kid. I don't know when we'll be able to go again (hubby and I) due to the new location and jobs with less vacation. I was very blessed to count on that on something my family and I would do every year (or every other year). Many happy memories

3) I'm already a sap for Christmas!! haha
Sigh.
