I'm so happy that you've been invited to join our sisterhood!
I guess in deciding between the two groups, is there one that you feel more of a connection with? Do you feel like you have more in common with the members of one group than the other? For example, I visited two chapters while a PNM. One had women in their 30s and 40s, the majority of them had kids. They were nice, but I really couldn't see myself in the chapter. The other chapter (that I eventually joined

) had members in their 20s and 30s, some were married, some single, some with kids. I felt like I fit in better with this chapter. Sometimes you can just tell, you know? I guess the big question is, with which chapter do you see yourself fitting in with the best?
Hope I don't sound like a bumbling idiot. If you want to talk more, you can PM me. I can't wait to hear your decision!!
