What would you do?

Sometimes I suffer from indigestion of the mind. ~Carrie Latet

Today the trash men came.  Bob and I had carried all the stuff to the curb which I threw out as I cleaned the garage.  I was really proud of myself, I only carried back three items back from the curb!    However my mind keeps thinking about one item I took to Goodwill.  Actually I took a lot of stuff to Goodwill, but my mind keeps reminding me about one specific item.  Should I go back to Goodwill and buy it back?  What would you do?
