Wish granted, but you have no watch to tell when the hour was over and I cannot look at my watch since you blinded me with your fluorescent green Ferrari.
Granted, but your most annoying relative comes round and wants you to help them fill in a seemingly endless tax return, all the time chattering non-stop with gossip about people you don't know and picking fault with your home and furnishings till late evening.
I wish I could come up with a great plot for my 2nd novel.
Wish granted, but on your way to the kitchen for a glass of water after 3 hours of writing, you slip on a banana peel your cat played with on the floor, you fall, hit your head and forget everything. You only remember an image of yourself at the age of 10. STill, you find some scribblings on your desk, read them and find them sooo retro.
