Yeah, I went the traditional way. He asked what took me so long to ask.
But my younger son's brother in law did it differently. He's a pretty good kid. Just got his commission in the National Guard. And wanted to become a cop. So before he asked her, he got his future FILs approval. Then he asked her two cop brothers for their approval, too. It seems that anyone with the class to ask almost automatically gets approval. It takes a real **** to not get it. On both sides.
And I only know of one situation where the old man said no. The couple were both nice, they were out of school and had good jobs. The father just wasn't ready yet to lose his daughter. So you know what the couple did the next day? Yep, they eloped. He apparently went to his girl and explained he wanted to marry her, but her dad said no. She wanted to get married too, so they did. I think that shows strength of character. I have no idea if either of my son's asked their prospective FIL beforehand.
