Memorizing the multiplication table was one of the most dreadful memories I have as a child. I know it's silly, but at the time it did cause me a lot of stress. Now I understand math is quite easy, compared to almost all other subjects!

I sometimes forget how old I am and twice I forgot whether I was born on the 26th or the 24th!

because of how I can Tetris any storage, shopping bag, suitcase, closet, bookshelf, etc.

Awesome sentence! :D
