Idio's

I'm drowning in a paperwork and dragging my feet about knocking it out, so I decided to come up for a breath of fresh air and blog instead.  If I could apply it, I'd add 'hit the books' and 'I smell a rat' to that sentence.
What are these little expressions called?  Idioms? Idiosyncrasies?
(yes, I now know they are idioms, thanks to google. Idiosyncrasies is a cooler word though.)
Which reminds me, and still makes me chuckle at my very literal four year old - Last week, after a night of little sleep, I was telling the kids to "please be quiet, you are making my head spin!"
Brant studied me carefully then exclaimed, "You're head's not spinning!"

We are still trying to figure out what to do in our dining/family room.  I decided our old computer desk had to go.  Our new desk fits in a little corner and does not hide my paperwork at all.  Hence my need for a life jacket.  How long has it been since I sorted, filed, and tossed papers?  Or cleaned off the computer desk? I think I am in need of some baskets or something with lids to hide all our CD's, USB cables, and other computer junk.

The bills need to be left in plain sight. How else will I remember to sit down every now and then and pay them?

By the way, did you know that it costs about $9,000 to have a baby naturally in a Hospital?  For heaven's sake, all I did was show up, push the baby out 45 minutes later, and occupy a room for two days! And I gladly would have gone home to sleep in my own bed a lot sooner had they let me.  I am too scared of the amount to decipher my bill for how much the Motrin cost.
(okay, maybe I should gripe about something else. When will insurance companies cover midwifery? And since I don't know if I'm brave enough - when will hospitals allow midwives to deliver?)

Perhaps I could say that this is just one of the idiosyncrasies of the hospital system.
