I always cry, but I try not to because of so many people around. The first time I visited England, I was at Heathrow and the security guy was very sympathetic, didn't ask me what was wrong. I've seen a lot of people crying at the airport. I don't think it's unusual at all.
The worst was when DB left here from visiting me around Christmas. I went to my car and didn't have to be around other people, so I really bawled.
It's been easier for me not to cry much with my February and April visits. I miss him and don't want to leave, but I've become used to trying to push aside how much I miss him. I do cry in the last couple of days leading up to the end of a visit.
Fireheart, we've all been there and it isn't unusual at all. I think you just got a difficult security person. (((hugs)))
