A sentence you always wanted to hear. Be it for you from someone (family/friends/pet etc) or anything that is not really approved in this world. Just anything which you seek to hear. Take it deep or funny! (not necessary that it has to be 15 words. Even 3 lettered "i love you" would work but to fill the word limit, do it alright!
From me to you
Do not let someone else's ignorance become the reason you deem yourself worthless. You matter.
