SOs "bestie"

Cara
We were together with family on Easter and my sister, cousin, SO and I were all sitting together and talking about dates because my sister was trying to decide if she was going to go to prom with this guy she barely knows...and somehow we got on the topic of the age we first went on a date...and my SO said he was 19...and it just slipped out but I was like not true you went out with your bestie when you were 16... My sister then said "Ya I don't like her"...my SO got so mad and was like you've never met her!...but I told him yes she has and his bestie was so mean and rude to her, and she's rude to me calling me names...so hopefully he figures out that she's bad news and needs to go.
