My sponsor picked me 3 1/2 years ago
I didn't know how it worked and she gave me her number. She then drove me to meetings for a couple months after I had my knee replaced. Finally one day she said "Am I your sponsor or what?" I thought she already was!
She is still my sponsor. I sponsored 2 teenage girls, 16 then 15, and I just picked up a new 20 year old sponsee. I learn more from them than they probably learned from me!
