Airport Frenzy

how do you forget your 3-yr in an airport?? And how do you not know this until 40 minutes later?? i'm talking about the case i just read about where a couple who had 5 kids were late for a plane, so they made a mad dash for the gate and they forgot their 3-yr old. that makes me mad you know! she was safley reunited with her parents because a flight attender assisted the 3-yr old on the next flight but still. the staff had to tell the parents that they forgot their child! that's crazy....
