father's day

so for father's day we went to the hana, that's benihana for you lay people, and it was really good.  But what interested me more than our crazy chef making indistinguishable comments about how i said medium rare, was the group sitting next to me.  There was a man and wife, that much was obvious, but then there was a girl who was not their daughter.  At first i thought maybe she was there alone, because she had asked me if i ahd been there before and i said no, and then the man from the, from the man and wife in case you got confused ha ha, was talking to her on and on about this and that, while the wife sat there looking completely miserable and pissed.  So I assumed that she wasn't with them, but then they all paid and left together.  So...i mean there is really only one conclusion...and that is a father's day threesome....right?
