For some reason, there're at least 5 Singaporean girls at my Hiroshima youth hostel (in a group of 2 and one of 3; there might be more hiding in the rooms but these 5 are those I've seen).

When the second group came in, one of them was unable to carry her trolley luggage up the stairs by herself, and one of the other 2 who'd gone up made some remark about getting the guy to help. She then publicly voiced her realisation that she'd been talking too loudly. I helped anyway, since there's nothing to do at night (there's an onsen but it uses artificial 'spring water' and I had dinner a bit too late).

Then later one was trying to figure out how to find the "@" sign; it was a Jap keyboard but on EN layout mode (the solution is to pretend you're using a normal keyboard and touchtype).
