I will start us off. I wish for a fridge that never runs out of my favourite food
Granted, the fridge never runs out because it is welded shut. I wish I could speak every language fluently
Granted, you speak all of them simultaneously, all the time, and nobody understands a word. I wish for perfect weather every day
Granted, perfect weather for slugs. Endless warm drizzle forever. I wish my phone battery lasted a week
Granted, the phone lasts a week because the screen brightness is permanently at 2 percent. I wish I never lost my keys again

Granted, everything includes every terms and conditions you ever scrolled past. I wish weekends were three days long
Granted, the third day is Monday, it simply joins the weekend while remaining Monday in every way that matters. I wish for a talent for gardening
Granted, you have an incredible talent for growing weeds specifically. I wish my wifi never dropped during a game
