I want to take a second to dissect that and talk about the "one bad apple". There's always one. That one who just gets under your skin, and you can't quite figure out why they behave the way they do, but it's really irritating to you. They're generally hard to get along with and prove to be your most difficult relationship. This person could be in your job, your class, your team, and a lot of times in your family. You know the type. Maybe you are the type.
I heard a pastor by the name of Kerry Shook refer to these types of people as "Sandpaper People". That is, someone in your life who has been placed there to help shape, mold, and buff your character. In my line of work, I'm surrounded by such individuals. Sometimes it's a challenge, but ultimately, I look at these people and whatever the situation as some kind of lesson. I'm going to share something that will help you deal with them, or yourself if you happen to be a SP person:
BE WHAT YOU SEEK
Let that sink down into your soul. What does that mean?
~Well for one, it means take responsibility and be the bigger person. It's not an "easier said than done" thing if you actually take it on and do it.
~Notice how you're being. Are you being cold? Distant? Standoffish?
~Understand that you cannot change anyone else. You just can't! So worrying about that person and why THEY need to change simply won't work.
~You must first examine yourself before confronting that sandpaper person. When you examine yourself, and how you're being in the situation, you then be the change you seek and you'll notice that those people are much more receptive.
If you don't deal with these people, they keep coming back. There isn't just ONE of those people you can't stand. They're everywhere! How do you deal with these people? By giving them exactly what you're looking for in return. You want Love from this person? Be loving. You want them to be kind? Be kind.
It's not going to be easy at first, but once you can do that, you've got the keys to the kingdom.
