Hah, my six year old doesn't have clubs. Apparently wants some though, I found him and the next door neighbor kid digging a golf hole under a tree the other day. Then they proceded to use a baseball bat to hit golf balls at it.
As for the "do you tell" question. I tell my friends and family, but it seldom comes up with coworkers. When students ask questions along these lines ("where did you find _____") I usually deflect on suits, shoes, etc., at least early in the semester. On more oddball stuff - cool cuff links or something clearly vintage, I'll say I saw it at a thrift store (even if I actually got it from one of you). Later in the semester, once they've decided who I am, I'm less evasive if they ask, which I've discovered only the thrifters in the class usually are.
