Life is about relationships. As long as you are alive you must relate with people. It is how friendly you are that determines your acceptance among people. I have met people who complain about not having friends in their lives and as you watch them closely you begin to understand why. They don't have friends because they themselves are not friendly! Here are a few tips on how to be friendly:

Be Approachable

Learn to interact with people. Be patient, gentle and tolerant. Don't reject others, because it is other people's patience towards you that has brought you to where you are now. You are not a self-made person, other people made inputs into your life to make you what you are today. So, learn to tolerate others. Tolerance is the grace for mutual coexistence. It is also an evidence of maturity. People who cannot tolerate others are often the biggest nuisance in the society. Never make yourself too difficult, rather be approachable.

Don't Make Yourself Untouchable

Let what touches others touch you. Jesus was able to affect so many lives because He was a man of compassion. Whenever he saw people suffering or in need, He reached out to them. It was not only the prayer of Jesus that brought Lazarus out of the grave, it was the compassion in His heart. The most hardened person will open up to you if only you would show him compassion. The largeness of your heart determines the number of people you can accommodate, which is also the number God will draw to you.

Make Room For Offences

Expect to be offended! If somebody offends you and says, "I am sorry", forgive him and put the issue behind you. If you can't forgive, you won't have friends!  Christ loves the Church immeasurably and unconditionally. That is why He keeps forgiving us every day. And that is the way we should love others. You can't have people around you and not occasionally have them offend you, so make room for the shortcomings of others.

If you understand and accept this principle, then you will be able to maintain your friendships.
