I was in a very long line at the post office recently. Had to mail a parcel to Canada, so couldn't go for the automated machine's shorter line. (The automated machine only takes domestic parcels as far as I know.)
Should have made my trip to the post office very early in the day, since it is the holiday rush, but didn't.
Should have brought a drop spindle to occupy myself, but didn't. Would have loved to have seen the reaction from the parent and child in line ahead of me.
Would also love to have had the nerve to sing carols in line, but didn't. Do you suppose anyone would have joined in?
