'BF' can mean boyfriend or best friend. 'DS' can be son or sister. You can imagine how some people's stories can seem a little "twisted" with a different interpetation of what 'S' means. Also some people use DD2 to mean their second daughter and others use it to mean the daughter is 2-years-old. I was shocked when a woman had DD2 still in an infant carrier. I read it as age 2. When I read it again I figured she must've meant daughter #2. It drives me
