So Apparently I'm a Disinterested Mother

I was feeling pretty good about myself when I went to pick Ironflower up from school. She had run cheerfully into her classroom two and a half hours earlier, waving good-bye while running to the kitchen area. Lovebug did not throw a tantrum as we left, he even held my hand willingly as we walked through the parking lot.

Lovebug and I had a nice time at the park. After moving between the sandbox and swings at regular intervals, I let him go on the "big playground", something he never gets to do with his sister around (neither of my children has the fear gene, nor do they have any fear of doing things on their own). He giggled as I followed him through the tunnel and across the suspension bridge. When it was time to leave, a promise of juice in the car was enough to quell his screams of protest.

He promptly fell asleep in the car and didn't even wake up when we pulled into Ironflower's school. Since her class was on the playground, I felt relief that I could leave Lovebug in the car. I was happily planning lunch as I walked up to the playground gates.

Ironflower ignored me. Even when I called her name. I chatted with the teacher and two other parents (whose children were more cooperative). I listened politely as they questioned the busy teacher about every minute of their children's days. I just wanted to get out of her hair, since I know she has another class right after Ironflower's. Finally, the teacher went to coax her over to me. Ironflower looked at me and yelled, "Go AWAY Mommy!" Talk about a touching moment. Her poor teacher had to carry her over to me as she protested loudly. I was finally calming her down and convincing her that leaving with me wouldn't be so bad when her teacher leaned over and said, "She had a great day at school, in case you're interested."

I was so stunned I just gave a fake smile and carried Ironflower over to the car.

IN CASE I'M INTERESTED? What the fuck?

I feel like telling her that of course I'm interested, but I've been a teacher and I know that pick-ups and drop-offs are not the easiest times to talk. I feel like telling her that as a former teacher I am simply APPALLED by her comment. I feel like telling her that she is a total BITCH.

Am I over-reacting?

ETA: Yes, yes I totally was. I was being over-sensitive because of Ironflower's temper tantrums.
