I locked myself out of the house

So I live Canada right now, and it snows often these weeks. I was home alone and my mamu( yea I live with my mamu for now, long story) called me to go check something outside in the storage if there was a gas can for the snow blower, and he actually told me to be careful and not get locked outside, I said yea yea i won't. I made a sandwich which I decided to eat after checking outside I left it in my room near the window, I went outside I left the door open and the fucking wind shut the door close, I stood there in silence for 1 min then started cussing myself out loudly and jumping in anger. I called my mamu with an innocent voice, got scolded then he called my massi to pick me up. The sandwich which I left in my room stared at me from the window, and there was I standing in the snow staring at it. Finally my cousin came and started laughing at me. 🙂
