Hating someone feels really really good...for about the first 5 minutes. Then, it starts to ruin your day. Trust me, I've been there. A hate so strong it consumes your every thought. "I'll show them!" Really? Are you really showing this person that you hate anything? You're stomping around being grumpy, snapping at anyone that gets in your way, and you sure are making a scene. But is this person affected by this show? Probably not. But boy oh boy I bet you are. No one wants to hang out with you if you're grumpy, and nothing seems to go right for you on a grumpy day either. So really this hatred is hurting...you. Try not to let your negative feelings toward someone else ruin your day, because chances are they're still having a pretty decent day, while yours is spiraling. If you really must show someone that you are upset with them, talk to them, tell them why you're upset, it'll feel good to get it off your chest. And then? Let it go! Don't hang on to this feeling all day, or your whole day will be ruined. Your "hatred" of this other person is hurting you, not them.
