I especially love this one: In Turkish culture you are expected to treat elder/older people with respect. It is common to kiss the hand of an elder person (a person you respect) and then touch your forehead with it. 

A tradition I really dislike is the wedding tradition. When invite hundreds or even thousands people to one wedding. When you are getting married, it is not your wedding but your parents' wedding (usually they are paying for it) so besides the relatives they invite THEIR friends and THEIR colleagues. Does your great-grandmother's cousin have a son-in-law whose sister is getting married? Congratulations! You have just been invited to the wedding.
