I know what you mean. Sometimes, when I have spent hours doing something fannish that gives me a big sense of accomplishment, and then people ask me what I've been up to lately, and all I can really say to them is "nothing much" because I really don't *want* them to know I spent 10 hours reading through stories at SSA looking for smutrecs I might have missed...it pretty much sucks.

Though I am open about my Smallville fannishness, just not so much the slash aspect.
