The bus driver probably hates me right now!

It's been an interesting morning over here. It started off with Nick oversleeping- he did manage to make it out to the bus on time. I got the girls up and we proceeded to get ready. About 1/2 hr before we go out to the bus, Halle asks when daddy is coming home. I tell her tomorrow and she got a little teary eyed but nothing too serious.
All was well until we are standing out at the bus stop and I see the bus coming around the corner. Halle starts crying and saying she doesn't want to go to school today.
I looked her square in the face and I told her- We aren't going to do this today. You are going to march yourself on that bus. She is still crying and the bus is now here. Arianna and Hannah get on the bus and I start walking Halle up to the bus and she's fighting me and crying. I ended up just putting her at the top of the bus steps and walking away- giving the bus driver an "I'm so sorry" look- I walked into the house.
I hate this- she loves school- I think she's just really ready for Mark to be home. She cried last night for him too. I know she's probably fine at school right now but I hate leaving her like that.
The bus driver (who was a sub no less!) was probably shooting daggers into my back as I walked away but I wasn't going to start that because she pulled that on me much earlier in the year and I don't want her thinking every time she cries I won't make her get on the bus and I'll drive her to school.
Thank goodness she doesn't have school tomorrow so we won't have to deal with it in the morning again!
