Can you kill plants too? Or does it not work in reverse?
I'm sure Yosef and Amichai and Yakov all love you and want to be your friends! I grew up with their parents and they're lovely people.
Good. Study Hebrew then and how it changes and is used in Torah. Have numerical fun with the letters and combinations too. You'll find some really interesting stuff hidden in there - I promise!
Some are. I could think of about 20 different things your power could be useful in, aside from just growing plants for the fun of it.
