hAPpy oR dISaPpOniTeD?

Someone said my voice is very cute like a child talking. should I feel glad or not.. I should feel happy or disappointed? But I feel not happy at all once I heard it.It seems like I am not mature enough.
I do not like people said I am still look like a child. especially some thought I am still in primary school. I will feel very despair an down although I wont show it through my face. I usually wont express my true feeling through expression. I will keep it in my heart. Some of the friends around me ( same age as me) looks mature..They know how to make up to keep them pretty. I am not envy them. At least they do not look like a child. BUT IT IS TRUE THAT I REALLY LOOK YOUNGER THAN ACTUALLY I AM! hao xiang zhang bu da der..Haihz..That is not my fault.
