Two old friends are sitting in a park. One of them tells the other:
- Do you want some ice cream? I will take a chocolate ice cream how about you?
- I want vanilla flavored ice cream. But, please write that down. We are too old we easily forget things.
- Don’t worry about that, the ice cream parlor is right around the corner.
After 5 minutes the one that started the conversation comes back with two hotdogs. The friend sees him and says:
- Where is the mustard?
- Damn, I completely forgot about that!
That’s why I told you to write down these things.
