You’ve been together for a while. Long enough, anyhow, for her to ask you to accompany her to a family funeral. You’ve dressed yourself up in your best suit and provide a sturdy shoulder to cry on. After the ceremony, as family members gather together to share their fondest memories of the deceased, you get down on one knee and propose to your girlfriend. Pick a moment where this can be seen by as many people as possible.
The Benefits : If she says yes, you know you have a keeper. If she’s willing to put up with you after this, you know you can get away with quite a bit.
Also : At your wedding, one side of the aisle will likely be pretty empty. Her parents and siblings will attend of course, but many of her aunts, uncles, and cousins will likely boycott the ceremony out of disapproval for your dickish stealing of their dead relative’s thunder, and selfish disregard of their greif. You will save money on catering.
