And just when I thought I was back to the #1 spot

Today I went to pick Ben up from school. This is always a happy time for me, I get to "rescue" him from school and he's ALWAYS so happy to see me.
EXCEPT FOR TODAY!!!
I walked in and grabbed his bag - I saw him in the restroom washing his hands with Ms Deb, and I hollered "HI BEN!" - and to my surprise I see his face go dark, a frown appear and tears welling up in his eyes. He says "No Mommy, Daddy is picking me up today"
hmmph - I think I've lost my position as #1.
