I have a loyalty that runs in my bloodstream when I lock into someone or something you can't get me away from it because I commit that thoroughly. That's in friendship that's a deal that's a commitment. Don't give me paper - I can get the same lawyer who drew it up to break it. But if you shake my hand that's for life.
On both 'The Bachelor' and 'The Bachelorette ' it seems like proposing marriage is equivalent to saying 'Let's date.' Everyone knows those aren't the same things.
