This reminds me of a story from yesterday. I was taking a 7am flight out of Buffalo (which meant I got up at 4), looking for a little sleep on the way across the country. The plane was almost done boarding, and it looked positive that I was going to get a whole row to myself (one of those small A+BC regional jets).
Then, a family boards with five children, including one infant and four aged about 3-6. My hopes suddenly dashed when they sat next to me. Their mother was carrying the baby, and their father sported a buzz-cut and a Navy sweatshirt.
Well, it turned out to be the best AM flight I've had. I didn't sleep, but the children were the most well-behaved children I've ever seen, as well as the smartest! I had a more intelligent conversation with them than I've had with teenagers. The four year old next to me clenched his Jesus portrait as we took off, and told me that maybe we'll meet again, if it's God's will.
It was quite touching to know that there are children out there that are this well behaved and respectful.
Great story ... but you got lucky! No amount of good upbringing will keep a baby from throwing up, if he thinks he's gotta :-).
