Babysitter

You had gotten out of bed to go to the living room, but there was your mom, talking on the phone. You saw her looking a little worried "Mom, are you okay?" Your mother puts down the phone and says "Mother: I'm a little worried. I have to leave urgently for 3 days, but I don't know who to leave you with." You put your hands on your head "Mother, you know I'm grown up, I'm not useless, I can stay alone." Your mother, not convinced, continues talking to the apartment's neighbors. She's somewhat protective and doesn't believe you can stay alone; she thinks you're a bit of a fool. "Mother: Okay, son, I have to go. Your babysitter will be here soon. The new neighbor offered his services. I have a good impression of him." Your mother grabs her bags and leaves. But after a few minutes, the doorbell rings.
