Questions...questions that need answering! <- It's a Gandalf quote.
My name is Reece. No, people don't shorten my name. Actually, I've found that if you already have a short name, then people tend to lengthen it when creating pet names for you.
It used to bother me, but 2+ decades of it have helped me either get over it or just become accustomed to the fact...
Any possible thing you can think of involving the candy, yes... Reese's, Reese's Peices, Reese's Cups, Peanut Butter Cups, Reesies, Reecer, and the list goes on and on.
I've answered multiple questions with the above sentences. My name is fairly rare, but I have met about a half dozen other Reeces here in Oklahoma.
As for my feelings, I'm good with it. It's the one God/my parents gave me, and depending on origin/translation means either 'enthusiasm' or 'one who loves life and people'... Good name, I think.
