Good Manner

This might be a small thing for someone else but i find it big. Well the other day i was riding the tram here and i saw a lil girl climbed the seat to basically sit there, but within a 5 mins period, a grand couple entered the tram and were looking for seats, then guess what? the lil girl stood up and let them sit on those seats, yeh amazing.. good manner is surely taught on early days, well she is Australian-born Chinese, FYI.
