A big pain in the Ass. That always gets you into trouble when you are younger. When you are older it is the greatest feeling in your heart and every inch of your body. It is the air you breath, it is a touch, a kiss, a loving glance. Your family and spouse.
Love is best defined in the bible at 1 Corinthians 13:4-6. it defines love: " Love is long-suffering and kind. Love is not jealous, it does not brag, does not get puffed up, does not behave indecently, does not look for its own interests, does not become provoked. It does not keep account of the injury. It does not rejoice over unrighteousness, but rejoices with the truth. It bears all things, believes all things,hopes all things, endures all things. Love never fails" . I believe this is the best well rounded definition of true love because it is God's letter to us the Bible and he created us with the capacity to love.
