:
Once I pranked my friend (имя друга). That was very funny! When she/he was sleeping, I put some toothpaste on her/his face. I was very worried, because she/he could wake up at any moment. You should have seen her/his face when she/he woke up! She/he just took a nap in my flat, waiting for food my mom was about to bring. Every time I remember that occasion, (если говоришь вслух, засмеяться) I can’t stop myself laughing! (Имя друга) didn’t feel bad, and we both had a good laugh.
