So I'm in the process of asking a few of my friends to be bridesmaids. One girl is my childhood best friend. We haven't seen each other much over the years, but every time we see each other its like no time at all has passed and we are clearly still each other's first best friends and love each other. She will definitely say yes. Thats not the point though - she lives in another state and I was going to mail her a little "bridesmaid proposal" box, but I don't have her address. I can't text her to ask because it will be too obvious and I want to surprise her, and don't want to say I'm sending out STDs because I think it will hurt her feelings if she thinks I never asked her (and I don't want to hurt her feelings for even a second!).
I messaged her mom (who is invited) online asking for it, but I don't think she checks her FB often and hasn't responded. I was thinking of asking her sister, but I'm not planning on inviting her. Do you guys think thats rude and I should find it another way? Or do you think its fine?
