New lesson #5 (Introducing people #4 - At a party)

1. FORMAL INTRODUCTIONS
There are several levels of formality, as an example we take:
'Nice to meet you.'
Douzu yoroshiku onegaishimasu (very formal to a higher person)
Yoroshiku onegaishimasu (to a higher person)
Douzo yuroshiku (to an equal person)
Yoroshiku (to a lower person)

2. HONORIFICS
The honorifics 'o' and 'go' can be attached to the front of some nouns as a formal way of saying 'your':
o-kuni = someone else's country
o-namae = someone else's name
o-shigoto = someone else's job
go-senmon = someone else's field of study

In some cases it does not mean 'your', but is it used to make the word more polite:
o-cha = (Japanese) tea
o-tearai = toilet
