Answer:
I have one that is effective.
Step-by-step explanation:
Your friend wants to have a hamburger for dinner, but you want to have pizza instead. You should talk to them about maybe having pizza this night and maybe a hamburger the next night. But, they don't agree with you. Then you decide to compromise with them. And, you have both. First you being a nice person go to McDonald's and get their hamburger, then you get your pizza.
I hope it works
