The flight is busy and the last few passengers to board are searching for places to stow their hand luggage. The Asian woman in the seat next to me is in her late twenties, probably travelling on business. She's wearing an expensive perfume which seems familiar though I can't quite place it. I am wondering if I should talk to her when the man in the window seat shows up and we have to let him in. She settles back in the middle seat. When I try to strap myself back in I find she's picked up the buckle of my belt by accident and we look at each other and laugh.
