For a proposal like this one to go over well, the asker certainly has to know his girlfriend well.
Nathan Evans, 26, of Bracknell, England, asked his girlfriend, Angela Olano, 21, to marry him in the middle of a Wiltshire field.
Actually, a banner on a cow asked Olano to marry Evans.
Evans took his girlfriend of 15 months on a country walk. Because he knew Olano loves cows, he borrowed a show cow named Rosie — bathed and clipped for the occasion, wearing a "Will you marry me?" banner — to help pop the question.
"I like cows, if I could have a cow I would, so I just thought he was going to take me for a walk somewhere to look at cows," Olano told BBC News.
"So I was really amazed but it really means a lot to me. I know Nathan is the man I want to marry."
The couple will wed in September. Beef will not be served at the reception.
When it comes to personalizing proposals, a girlfriend with a cow obsession is certainly easier to accommodate than one obsessed by The Proclaimers. One man walked 1,000 miles to "fall down at her door" and propose to his girlfriend.
Oh, the things we do for love.
