I'm thinking of feeding my vegan nephew meat
Why would you feed him meat if he's vegan?
It will be hilarious! The look on his face will be priceless after he will realize that I gave him meat!
You want to play a mean prank on your Vegan nephew, but this will be more than just a prank. It will mean he never eats your food again, and then probably not even want to talk to you either. Stop that thinking, and be a mature adult for once, Vegans take their food restrictions seriously!
Aww come on. It will be hilarious.
I don't think it will be funny, I'm sure your nephew would be devastated if he learned you fed him meat. You should consider his feelings in this.
