Also, I won't have to bother myself thinking so much about where some stuff are kept because every inch of my home would have been memorized by me and I'll know just where things are kept.

This part is an added advantage truly. For people that love their things where they left it, managing a small house will be much easier indeed. I'm sorry that happened to your mum. I always believe everything in life happens for a reason and thankfully, you picked a lesson from that incident.
