DAD: Do exercise 5, question number 3, 4, and 7.
[a few minutes later]
ME: Here it is!
DAD: [ONE TIGHT SLAP!!!!] You can’t even do such an easy algebra question. You missed a negative sign in the answer.
ME: (while looking at my notebook) (sobbing) But I have a negative sign there!
DAD: You have such a bad handwriting, son. Go and write a page in English and that should be in good handwriting. We will do algebra after that.
