I was watching The Return of Superman, when the naughty Donggook appa plucked Seola's hair and tickled Sian with it. I laughed at how he's so naughty. Then I got reminded of the times my dad used to play with me. He was one naughty dad too. And sometimes I kicked him in retaliation on the bed. As time went by, my kicks got stronger but he got weaker, so I could not longer kick him with full strength anymore. I suddenly felt so sorry for kicking him so hard. I miss daddy so much. It sent a flood of tears.
