I greet people differently depending on who I greet to. For example, I greet my friends by just saying like "hi, good morning." However, when I greet to superior or elder people, I bow over saying "good morning." Also, I greet with honorrific words to them. For example, when I say good morning(ohayo), I add "gozaimasu" after that because it's more polite.
When I talk to people, I rarely touch them because if someone touch me when he/she talks to me, I feel awkword, and I don't want to make people awkword.
