Some magazines require you to send in your completed manuscript via snail mail . . . they often tell you to include a SASE (self addressed stamped envelope) if you want your manuscript returned if it's rejected. My question is: Is it considered a mark of naivete and unsophistication to include a SASE?? Should I just relax and know that if they don't use my work, they'll just shred it or throw it out? Something deep down inside me feels uneasy with my work just floating around out there. Could one of you more experienced freelancers put this in perspective for me? Thanks.
