Yes!! Love is like a cancer because it attaches you to someone and his /her picture become attached to your mind moreover makes this person as your heart when he/she feels happy you feel happy and when he/she feels sad you feel sad anything doesn't matter except giving him/her whatever he/she needs even if this thing will be on account of your own happiness yes this is love!!. This is the disease that we catch it's infection easily and fast sometimes with a one glance. But sometimes we don't feel all of the previous until you lose the one you love.
