Yes, I have . Your enemy sometimes know even better than yourself . It is better to have some enemies .
Of course I have, everybody does. Those of you who think they don't have enemies should reconsider.. If you are mean - you'll have enemies for being mean; if you are friendly and nice - you'll have enemies for being friendly and nice; if you're in the middle - guess what - you'll have enemies again
lol.. I would think that rings true for most people.. I am currently accepting applications for sworn enemies..
I got my friends and aquaintedes the rest I would consider my opponents until they become one of the prior 2 of course.
