Reading questions, Gorky's "childhood"

One day, the owner of the tavern quarreled with her grandfather. She also scolded her grandmother, who did not participate in the quarrel. She scolded her very fiercely and even threw carrots at her. "You're so muddle-headed, my good wife." Grandmother said to her peacefully, but I was so angry that I decided to take revenge on this evil woman. I thought about how I could give this red-haired fat woman with a double chin and thin eyes a more painful blow. I observed the infighting of the neighbors, and knew that they would take revenge on each other by cutting off the cat's tail, poisoning the dog, killing the rooster and hen, or sneaking into the enemy's cellar in the middle of the night, pouring kerosene into the cask of pickled cabbage and king melon, and releasing the kvass from the cask-but none of these were to my liking; I needed to think of something more astonishing and powerful. I had an idea: when I saw the hostess go down to the kiln, I closed the top of the kiln and locked it. I danced an avenger's dance on it, threw the key on the roof, and ran to the kitchen where my grandmother was cooking. She didn't immediately understand why I was happy, but when she did, she slapped me hard on the butt and dragged me out into the yard, telling me to go up to the roof and look for the key. I felt strange about her attitude. I quietly took the key off and hid in the corner of the yard to watch her release the captured tavern mistress. The two of them walked across the yard in a friendly manner, laughing. " I'll show you what I'm capable of," the tavern mistress said threateningly, clenching her fat fists, but her fat, blind face smiled kindly. Grandma grabbed my collar and pulled me into the kitchen. She asked, "Why'd you do that?" "She hit you with a carrot…" "Are you doing this for me? So that was what happened! You'll know when I feed you to the rats under the stove! What kind of protector are you? You're just a small bubble that can be broken with a poke! You see, if I tell my grandfather, it would be strange if he didn't skin you alive! Go study on the top floor…" She ignored me all day, and in the evening, before praying, she sat down on the edge of the bed and lectured me with words I would never forget: "Aliosha, my dear child, you must remember not to meddle in the matters of adults! The grown-ups have gone astray; God is testing them, and you have not been tested, and you ought to live like children. Wait for God to open your heart, to show you what you ought to do, to lead you on the path you ought to take. Do you understand? As for who made what mistake--that's not your business. This was for God to judge and punish. This is his business, not ours!" She was silent for a moment, sniffing her snuff, squinting her right eye, and then added, "Yeah, even God probably doesn't know who made a mistake all the time." "Doesn't God know everything?" I asked in surprise. She replied softly and sadly," "There's probably a lot of things people wouldn't do if he knew everything. The old man looked down from the sky to the world, to all of us, and sometimes he would cry and say,'My people, my people! Oh, how I pity you!" She cried herself. With tears all over her face, she went to the corner to pray. From then on, her God was closer and more understandable to me. 1. Why did Grandmother hit me? 2. Why doesn't Grandmother want me to meddle in adult affairs? 3. From then on, her God was closer to me and more understandable, how to understand this sentence
