Again, bad attitudes are contagious. If the people closest to us, including family, friends, and coworkers, have negative attitudes, you may "catch" one as well.
Just remember, you don't have to get upset if someone is trying to make you upset. You can choose to stay happy and upbeat. I like to think of this as wearing a bulletproof vest. People can fire negativity at me all they want. But if you remember that it is their issue, not yours, it should bounce right off you.
