Awwwww. My grandparents are somewhat like that with my lab. Somedays it's "aww poor ol' girl" and some days it's like "Stupid pain in the *** dog. GET OUT OF MY WAY!". More of the first than the second. She does like to walk in front of you and then just stand there when you're carrying something, so it's almost understandable. I guess my point is, I'm really sorry for your loss. I sort of feel your pain, though my girl hasn't left me yet, thankfully.
If we are made of cells, then a scientist who studies cells is actually a group of cells studying themcells!
