I am always skeptical of anyone who has the nerve to ask for something from a stranger.
I did get a furled leader from Betty a few years ago after I posted a thread about having bought one and was impressed with it. I loved her furled leader and told her so. That act of kindness got me into furling my own leaders and I now give them away to the few fly fisherman I run into around here.
What I'm getting to is that not all acts of kindness are taken for granted.
