Polite young man

Today I saw a boy getting up from his seat when other adults got on the bus and it was gettign crowded. Not elderly people, just people. This is lovely, and somethign that should be a given but more often than not noone moves from their seats for anyone. It should not be this way..... and good on this young man for doing it. Good manners!!!  I am sure I sound like a 90 year old woman now but I firmly believe we should get manners back into society!
