When im sad

what would you do if you sad? my mom always told me that you should remind about things that can make you feel happy, and i did it, i always remind about my mom, the most unbelieveble person in this world. I always active and always ask about anything, i remember one days when I m asking something that i dont know, and i ask her, she knows this world better than me, but one day i ask something that make her quite and say "honestly i cant answer your question, its difficult for me and its beyond my understanding about things, i tell you this, you must remind this question and you will find the answer and you must explain to me about it" well i dont know each time she said that, it makes me want to grow fast and know about everything, and i can explain it to my mom.. and one day i ask question to my mom, "mom, what happen if i can't found the answer to my question?" she replied "don't worry you will, as long you have faith you will find the answer, the problem its you satisfied with answer you already find or not. sometimes things happen without any reason, its just happen..." and i come up with another question :) "how do i know, if the question come up without answer or with an answer?" (I know i sound fussy that time) and my mom just replied "then you will the one who will explain to me..which question had an answer and which one its not"

when my mom told this story to me, I even said that im a jerk that time always asking questions.

well mom, one thing that i never find an answer, why you should leave. The question that i will never find the answer, the only thing i know I miss you, and its make me happy when i remember things about you ... ^^
