What do you think about me taking advantage of my friend's confusion?
How are you going to take advantage of their confusion?
I'm going to pocket some her possessions.
You should not take advantage of your friend. Stealing from your friend when she is confused is rude and illegal.
I just love to see her suffer. I've been thinking of ways to do so.
If you love to see her suffer, then I don't think you're really her friend. Friends want to see each other be happy and do well, not hurt them by stealing from them or otherwise being mean to them. I think you should try being nicer to her.
