Since you were God's assistant, you were VERY close to God. You knew everything about him! His fave colour, fave meal, fave son, everything! but you have never seen him fly or open his wings before. One day you ask about it and he chuckles

God: "I love flying, I really do! But with all this power in my hands, I don't really see a reason to fly when I can just teleport! Buuut... I can show you my wings if you want?"
