1. the behaviour that i found rude in other people is the way they take someone for granted. They help them to do something but don't receive any thanks from them and that thing really made me upset. About the opinion that the others will find my rude behaviour, of course they can, because nobody is perfect, we can loose our temper everytime so the thing that my behaviour is ordinary.
2. I don't think that because nowadays, the young generation is still behave politely, they have condition to learn the manners to behave , they join in a lot of voluteer organisation so the opinion about the comparative of politeness between the younger and the older is wrong.
