If you find a magic lamp and free the Genie inside, which would your three wishes be?
Now that the exceptions had been stated, I guess I could just settle with the following. I would like to have my own invisibility cloak. I've always wanted to have the power of invisibility. I could go to places I like without having to worry whether I am allowed there or not. It would also give me the freedom to do something, maybe go outside for a swim in the lake, and the like.
For the second wish, I would love to have my own Room of Requirement. There are certain times that I really need the secret room but it is being used by everyone else. There's Rorey for her diamond counting, Ryan for his supplies of muggle weather equipment, Fu's secret coffee factory, and Tarma's snitch practice session, among others. The demand for the Room is so high that I could not enter it for two months straight. My own Room of Requirement will solve that problem and I can sleep quietly, at last.
For my last wish, I would want to have an unlimited supply of Felix Felicis stored in a classified magical place. For obvious reasons, I would want good luck. For example, in job interviews or in crucial reports, also in situations that would require luck such as disease, emergency situations, among other scenarios. I could also use it as gifts to my friends, to share the luck. Of course, I will regulate my use to the right scenarios that demand its use.
