Interpersonal refers to something involving, or occurring among several people. Interpersonal skills refer to our ability to get along with others.
The adjective interpersonal really only has one meaning, so when you hear this word, you know you're hearing about interactions between people. Sometimes corporations find it useful to train their employees on any interpersonal skills they may be lacking, especially if they have a group of really socially awkward people, because it really does make the work environment a lot easier if your coworkers all get along with one another. In the same way As is rightly said, “A friend in need is a friend indeed”. Friends are an important part of every individual’s life. You talk with them about every damn thing; share your top secrets and what not. You enjoy with them and spending time with friends is fun always. Everybody would agree that had friends would not been there, life would be quite boring. In fact, whatever you are as a person is greatly influenced by who your friends are. So, friends are truly important. They sometimes teach you, make you learn new things, point out your mistakes and help you rectify them, cheer you up as and when needed, offer you a fresh perspective and always love, care and support you.
