father?partner?

so something funny happened today in class.. ther were oni 3 ppl at the beginning of lesson today including my lecturer and then we all were sorta chatting abt gangnam style .. and suddenly, the another gurl said tat gangnam style's dance is usually popular among ppl 50 years old and above.. and i replied:" yeahh, i thnk dats true cz my FATHER knows how to dance yet i dont." and then somehow, the lecturer heard "PARTNER" when i said "FATHER".. so he asked:"heyy, how old r u actually?" and i answered:"im 19". then he said sumthng really.. well.. funny.. i guess, he replied:" so ur PARTNER is much older than you are?" and i was like..." errr... no..", he:"so he's not above 50?" me.." err.. no..." and then he was like:" ohhh.. but u said jz nw that ur PARTNER is above 50?" ...... me.. " ohhhh.. that was my FATHER.." and so i was laughing and the lecturer was also laughing and said to another gurl(who is also laughing): "ohhhh!!! no wonder u were so quiet about it..!!" and so we all laughed again.. to be honest, it was pretty embarrassing.. -.-
