Time-periodic thumping

I am just curious. I hear a constant thumping sound from the back of my room in Gage, but I am just unsure of what its source may be. I think it might be people having sex in the room next door, but it happens so often and is so constant that I am having a hard time believing that.

Somehow, I think that little jewels like those are what I will finally miss the most when I do leave the residence hall for good sometime soon. Kudos and hats off to you, my brave neighbour. You go, dude. Reach for the sky.
