Birthday Celebration
When Winston learned that it was Ai's birthday he insisted on baking her cake. While making the cake he kept getting angry at dad for wanting to 'taste' the mixture. Winston added the frosting and chose the candles. Penelope's contribution was to help Ai blow the candles. I think she thought it was her birthday again.
Unfortunately we didn't have powder sugar so I looked online for a cake frosting recipe without it. Much to my surprise I found one. It was not good at all but the cake was good.
