I asked my stepmom to smell the flower because it had a bee in it
Why would you ask her to smell it if a bee was in the flower?
I wanted to hurt her and this was a good way.
You shouldn't try to hurt any member of your family just because you don't like them. She could be allergic to bees and have a reaction to it if it stings her. You should try and be more caring.
Meh, I just wanted to see her freak out.
This little bit of fun could have been dangerous and land your stepmom in a hospital. Try to work on your relationship with your stepmom rather than hurt her.
