I am fine as a non-cow entity, thanks. I choose FLEE FOR YOUR LIFE
Would you rather....
1. Every 3 months you can go back in time and have a one-hour conversation with the historical figure of your choice, in the setting and context of your choosing (being able to understand each other perfectly).
The cost of this power is that when you are in the present a tearful person will forever more follow you around, looking very concerned at you as if you are terribly upset but are managing to bear it well. Generally, they will keep their distance but from time to time they'll come over with a hanky and dab it at your eyes as if they have just managed to prevent a sudden upwelling of tears and blow their own nose. If someone asks you or them what is wrong, they won't speak, but begin to noisily weep and break down as though the very thought of it can't bear repeating - and the asker should know better than to bring it up. You will not be able to tell anyone what is going on.

2. Once per day you must summon 500g to 1kg of 1 item of food. For example, some truffles, pastries, carrots, rice or anything. Full meals don't count. They can be cooked or uncooked and must be consumed by you.
The cost of this power is that the food item is brought to you by a very swarthy looking person. They will follow you around for 10 of your waking hours. You will need to share the food with them. They will evilly chuckle and look at you knowingly (and the food whilst it is near you) as if to suggest that there is something very sinister about what you have done or where the food came from. If anyone asks you or them what they are doing there they will laugh in quite a maniacal fashion and look from you to them in astonishment that you haven't explained what's going on. You will not be able to tell anyone what is going on.
