I never used to cry, but in the past year have become quite the flying weeper. My fiance lives in the UK and I live in the US and we say goodbye in airports all too often. It's just a part of our lives right now, but I just can't get used to it.
Everyone is nice to me and asks if I'm okay, and I nod and explain briefly and people are very cool about the whole thing- in fact, it often leads to interesting conversations about their long-distance love affairs. I had a very pleasant chat with one of the security people at NCL while she was looking in my bag to check some embroidery scissors just a couple of weeks ago. I've never had trouble in security because of it and find that people are very kind.
AND, I can be distracted. Once my fiance was in Uruguay and I was departing Montevideo to come back home and in the security line, a Uruguayan woman distracted me by telling me about all the food she was smuggling back to the States. By the time I got to the gate, I was laughing.
So...if you see a weepy woman in line at security in NCL, on a plane departing NCL or walking away from security at IND, it's probably me.
