Usually I don't like big funky proposals because they seem to be all about the guy proving how funny or clever he is and it isn't about the woman. But this one works so differently.
Maybe because you can tell that his parents and her parents are in there. As well as other relatives.
Maybe it's her constant laughter and delight.
Maybe it's the tissue box they put in the back of the car just in case.
Whatever it is, this video delights me and makes me mushy every time I see it.
