Quite possibly. She seemed really whacked out. Her husband seemed to want to crawl into the woodwork. But before they started to board, she seemed "normal".
I think she got her panties in a wad because she felt "slighted" because as she put it "we were waiting here first in line before all these pther people." They weren't boarding wheelshair pax with 15 members of their extended family. Of the three I saw be preboarded, two were eldery with two other adults with them, and one was a woman who looked to be a para, her DH and one child. Did this nutjob really think they would have to sit in the back of the plane because nine people got on ahead of them?
Personally, the whole idea of preboarding anyone with kids not in a car seat is ridiculous to me. Anyone with an A pass should have no trouble finding seats together, and if you're too lazy to check in the day before and get that A pass, then too bad, fly a legacy carrier with assigned seats. But that's another thread. (Disabled individuals on crutches or using a wheelchair are another story entirely, and IMHO they should always be preboarded, but should also always expect to be last off.)
She seemed to be getting herself more and more worked up, and then just toally lose control. Oh--and I think she had high BP--like through the roof. She was overweight and her face ws very red like people with high BP often have. She's not going to live to see those kids out of elementary school if she doesn't get control of herselfe physically and mentally. I feel bad for her kids.
