Is it really your birthday? Are you really 2 years older than me? Well, actually it's closer to 1 year older~ but just because you're 1 year and a month older merely means that it seems like you're 2 years older for a month. See, if you look at it like that then, well then things start to become very flopsie. Because just imagine. If I were to turn 19 one month before you were to turn 20 the illusion would be created in reverse, that is, if you're not lying about your age. See, in the end....it all boils down to that.
