My Brain Hurts

So today I learned to much about the circulatory system and how blod clots!! It's not enough to have to learn that the blood leaves the heart & lungs and takes the oxygenated blood to the tissues, I have to know every artery on the way!!! And every vein on the way back and it's not enough to know that platelets cause clots but I have to know how platelets are formed and every protein and enzyme in the process! I am a little overwhelmed!! I guess its good that I get paid to learn all this! The kids had a friend over this morning and they chalked every brick along the sidewalk!!! I think it actually looks nice! Derek was standing beside the for sale sign this afternoon! I think sales is in his blood-he gets it naturally from me!!! It may work to have a cute kid standing beside the sign because a young girl drove by and wrote the number down!
