I wear my "Keeper" lanyard to DL all the time with my Ariel pins on it. Why? Because I LOVE Ariel. My sincerest apologies if anyone interprets it as a "I have this and you don't neener neener boo boo!" ... That's not my intent at all. I do it for ME, no one else really
Also, I've had little kids ask me "Are you trading those?" and I very politely say "No, they are just for me, these are my special pins" and I don't get disappointment at all. On the contrary, I then get 20 questions xD "Do you REALLY like Ariel?" "How many Ariel pins do you have?" "Which is your favorite Ariel pin?" "Where did you get this one?" "Do you like her better as a mermaid or a human?" and usually followed by "MOM! DAD! Look at her Ariel pins!"
As for the original question, I usually bring my few traders in my pocket when kids do ask to trade. I typically trade just because even if they have nothing that grabs my fancy, I consider it a trader for a trader pin. What REALLY hurts is when the kids have all scrappers... o_<
One cute little girl wanted to trade me an Ariel pin (seeing as how I obviously like Ariel) for one of my Tinker bell traders. She handed it to me and I KNEW it was a scrapper but didn't have the heart to reject her pin trade offer and tell her that her pins were fakes. I was like, "Oii...er...okay... THANKS! ^_^; "
