Uhhhh...
I don't mean to sound picky, but, "spinsters?" Really?
Might as well say, "Hey all you hopeless old hags out there, I see you in your rocking chairs, knitting and feeding those 16 cats... Give me a call! Wink, wink, wink."
Um... Sorry... again, I'm not meaning to criticize it just seems like there would be a more positive (not to mention flattering) way to address strong, independent, single Christian women?
