What is so funny, is I can’t even tell were it’s coming from, but there must be a vent or something. It’s really only happened a handful of times. One time that I remember, I had Photoshop, Illustrator and Lightroom open AND my photobucket page with a bunch of gifs all going. Those programs are huge and my MacBook seemed kind of angry about the whole thing. Once I shut down the photobucket page, it stopped.
Wow, you had a lot going on! (very excited about my new husband)
