I know it's overused to the point that sometimes it's only said out of gesture or expression, but I have (recently) learned to say it only when I truly mean it. I am aware that you deserve more than my kind of love to you. You are due far more than my half-hearted replies of happiness to time spent together. You are worth more than this conceit that I constantly show. You are a truer bundle of sunshine.
Know that even though it pains you whenever you remember that time is very limited on us, I carry with me that moment you spoke for me.
