This sounds weird, but I'm excited because I'll have some free time tomorrow to do some deep cleaning on my apartment. It's been messy since I've been gone most of the summer. I want to get it clean before school starts so I can enjoy it being fresh during the semester
Nothing like a deep clean to breathe new life into your home! Its a great idea to get it out of the way now so it won't me on your mind once things start to get busy. 
Yeah, I'm the type of person to get stressed out and become unable to work in an environment that's too cluttered or dirty. It starts to make me feel claustrophobic. I have a good gene I guess, because cleaning relaxes me, while to others it's like a chore.
I completely understand that. Its a good quality to have and is actually healthier in the long run if you keep your surroundings clean.
