Aw Nancy.... that's so nice. The whole sequence of events is heartwarming! Who would have thought you would be thankful for a flat tire? I love RAK's. Some of my favorite truly random acts include: giving someone the cart at Aldi and telling them to keep the quarter- this never fails to get a smile and a big thank-you letting someone with a few items go through the check-out before me having a good conversation with a server and leaving a big tip. holding doors open. costs nothing and almost always gets a smile.
