I don't think anyone ever said life was meant to be easy. It's definitely easier for some than others. Sometimes.
Sitting aboard a flight to Belfast and enjoying what was actually a good cup of green tea made the 5am start and the hideous experience of Luton Airport bearable.
You can either whinge and moan about stuff or you can just see it as a mean to an end.
I hate wheely suitcases, especially at airports and stations, when people don't seem to know where they're going. But you just have to negotiate a route around them.
Same with queues. Necessary evil sometimes.
A bit of stress is probably a good thing for a brief period, as long as you can follow it with a mini relax. And I console myself with the fact that there is always - always - someone who's worse off.
