At least 10 sentences. Topic: Pranks Have you ever pranked a friend? Have you ever been pranked? Do you like pranks? Can pranks
Digiron [165]

Growing up i have witness alot of pranks and pulled a few on my own that is why i am very fund of pulling pranks. I feel like pranks are a way for people to show off there creativity. For example, my friend ( enter friends name here) pulled a prank on me were she pretended to lose my phone. I was upset at the time until i realized he/she had a weird bulge coming from the side of there arm. My friend decided to hide my phone in the upper part of there shirt sleeve. I was rolling around laughing once i realized my phone was in no way lost. pranks are always funny when there not extreme, try and pull a little prank for yourself. Just remember to make sure if something breaks or really is misplaced, you can re[place that item. Pranks are meant to be funny and harmless. never pull a prank that you would not want someone to pull on you. And if it does happen maybe you should reconsider pulling extravagent pranks, or ask that person in advance if this would upset them and pull the prank on a later date once they have forgotten you asked about it.

hope this helps
