I had none and she wouldn't let me alone. For months she kept asking me to show her my rejection slips and I got sick of her nagging. Finally I sent something I'd written as a little kid to a publication I knew couldn't possibly accept it. Sure enough, I got a rejection slip, showed it to her, and she let me alone.
Years later after getting the first thing I'd ever submitted published right away I began sending out other manuscripts and getting - you guessed it - rejection slips. That was a bit disappointing, but also exciting because they showed I was a real writer.
I've been grateful to that roommate, Sheila Walsh, ever since and wish I could get back in touch with her to express my gratitude.
