Every once in a while something nice happens:
Today I had to visit Lenscrafters for what feels like the millionth time this year. My son is autistic and totally destroys his glasses frequently. When they asked if we wanted new lenses with the new frames I blinked back tears and said quietly, "We can't afford that, we can barely afford the frames." The technician looked at the computer screen and said, "You have quite a file here with him. Tell you what, I'll throw new lenses in for free." and it totally MMD!
