All the best in Singapore. I used the little bottles of water-free hand wash in the train or aeroplanes when I was going to handle my lenses. Great, but can make your hands a bit dry, so it would probably be a good idea to have some of that other stuff that puts the moisture back afterwards.
Now that I don't wear lenses I tote about less of the girly stuff than I used to

. My cosmetics bag was bigger than that of my wife when we got onto aeroplanes!
Reminds me of the story told me by Tom Winning, just after he was made a Cardinal (I wanted to say 'promoted', but I am not sure if that would be right.)
TW had to go to New York to attend to some business. While there he was going to celebrate the mysteries in a New York Parish, so he took his travelling vestments. These included a lace surplus that had been made for him by a lace-making parishioner of one of the Parishes in the Arch-diocese.
TW's flight was slightly late arriving at Kennedy, so he hurried by taxi to his hotel, checked in and then rushed by taxi to the first of his meetings.
Back in his hotel to get ready for dinner, TW noticed that the staff had, very helpfully, unpacked his bag. Shirts, socks etc had all been stored in the drawers, his PJ's had been folded onto the pillow of one side of the massive King Sized bed. (beside his PJ's the domestic staff had put one of those little chocolate mints)
On the pillow on the other side of the bed the domestic staff had folded his lace surplus
Now that's how people start talking .. did you hear about the cardinal and Mrs Cardinal from Scotland ...
TW evidently told the story at the service he was sharing on the Sunday. Reactions varied from his own amusement to some folk who were mortified that a visiting dignitory had been embarassed in this way.
Well, my cosmetic bag when I was travelling might have provoked every bit as much speculation, if I had been accomodated in those hotels where you pay enough to have your bags unpacked for you!
