Has My House Always Been This Dirty?

Having more time on my hands means I'm noticing a lot more than I used to.  And while cleaning the bathroom today I thought to myself... has it always been this dirty?  I swear I feel like I'm cleaning more often then I ever did before.  I figure one or some of the following things factored into this:

1. I'm bored, therefore being more picky than normal on how dirty things are.
2. Since the house is on the market we have to keep it nicer than normal, therefore I feel the need to keep up with things more.
3. Since buying the house I have added a man, rabbit and a second cat... obviously making more of a mess... however our family has been complete for more than a year now, and I don't remember cleaning this much a year ago.
4. The house has always been really messy but with my work schedule I just didn't notice.  I know I'm not the only one to ever work overnights, or 50 hours a week.  I know other people do it, with kids, etc.... and maybe their houses are also messy.  But I thought maybe I was just too tired to notice the soap scum in the back corner of the shower, or the tiny pieces of litter that make their way down the hall.

So who knows what the reasoning is... I do know that I am enjoying a cleaner home.... but my least favorite chore is still cleaning the toilet!!!!!
