Salvation Army Anxiety

I drop off lots of stuff at the SA for tax deductions. Most of it is in good shape. I can park right in front. The volunteers are always helpful. It feels good giving to give to those less fortunate.
However, I have anxiety going there. The guy behind the desk knows me by now. I always ask for a receipt and he obliges. We don't make small talk.
But what if he begins to question how one guy could donate so much stuff? What if he looks me up on the Internet, digging for dirt. Maybe something about me makes him uncomfortable. Maybe he thinks I'm fencing stolen goods.
I know what I'll do. I'll make small talk like a normal person and smile. I never smile anymore since Perry Como died.
That's a separate issue.
