Ugh! About 2-3 years ago I was waiting around just before school let out when another mom approached me and struck up a conversation. She asked a lot of questions (What do you do? What's your husband's name? What does he do? Etc.) but friendly. I figured she was just really outgoing so I chatted with her. She started telling me how she had recently started her own business and she was so happy, etc. Then she dropped the bomb that she sold a weight loss program (food and supplements) and she'd love to discuss it with me.
Okay, I could have lost 25lbs (And have lost 15-20, in a safe and healthy way, over the past 18 months, thankyouverymuch!), but who does that?! I was hurt but politely declined, rounded up my kids and left. A few days later I started receiving invitations to add her on Linked (which I don't even use), Facebook, etc. She had used our names & occupations to track me down online and try to recruit me. I just deleted/ignored it all and avoided her at school functions. She tried 2 or 3 times then gave up.
Sorry you had to deal with that, WW. He's a jerk!
