If you want to keep your family in your mother's house, I suggest you communicate with your mother more first and tell her the living habits of my neighbor totoro and some complicated things that need nursing. Everyone will be happy if mother agrees. If mother doesn't agree, it's best not to buy it willfully. My neighbor totoro is very delicate, and it will be afraid, nervous and fearful if someone treats it rudely at home. And if your mother doesn't want to take care of my neighbor totoro, then your time is also a problem. I help my totoro clean up every day, and the total time for outdoor play is about one hour. You are still a student, don't delay your studies.
Anyway, if mom is willing to take care of the little guy with you, buy one. It can bring you a good mood every day in Doby. If you don't want to, it's okay. You can see lovely pictures in Totoro Post Bar and have fun ~ ~
