I mean, what does 'much shorter' mean? 2 days? 2 months? 2 years?
Is "your friend" thinking about marriage? Because if not, what difference does it make? He can keep doing what he's doing (which is what he's going to do anyway because that's what he's been doing for 2 days, 2 months or 2 years). If he is considering marriage, which woman does he think he can live the rest of his life with?
This is a classic case of some bullisht.
And I thought you ain't like the song Slow Motion???
