Great news! The flowers arrived! They were delivered around 1:00 and were exactly what I ordered. My friend said they're beautiful and they "really made her day" because it was a rough first day of school. She had a screamer/runner (1st grade), had no break from her kids from 7:15 until 2:15, and then two of her kids were left stranded when their parents didn't come pick them up.
I once thought about going into teaching but it's probably a good thing I didn't.
