Love strikes in an instant. A single action can make you fall head over heels. It doesn't require time, just a heart that beats for one person. When you know, This is the one I want to spend my life with.-that's love. Feeling scared at the thought of losing them-that's love. Their presence or absence affects your mood-that's love. And when they're the first person you think of during your toughest times-that's love.
