age gap

my cousin told me she wanted to introduce someone to me.  i asked, "how old?"

she replies, "36."

me:  'the previous one was 35; this one now's 36...'

she goes, 'ay, they're one and the same guy.  it's going to be his birthday so he'll be 36.'

eh?!  hello!!!  he does not have a monopoly of birthdays.  my issue is our age difference, not his age...
