Some of my favorite moments in the strip are when the characters drop their guard a little bit, and we see glimpses of their bruised humanity. It doesn't happen often, but those strips carry a bit more meaning than most.
If you haven't seen them before, take a minute to read the two-week storyline where Sheldon reminisces about his parents...or the two-day arc where Gramp thinks back on his his wife. They're both nice moments.
