Box lover

If you have experience keeping cats, you may know that cats love boxes. 
They cannot stop going into a box if they find one.

I can understand their feelings. When I was small, I also loved to go into a box. Staying in a box made me feel I had a special room, just for myself.
In my childhood, one of my favorite plays was making boxes with paper. I made lots of tiny paper boxes and displayed them in my room. It was quite fun. 

It may be a holdover from those experiences, but I still love to go in and see new buildings or houses. You know, these are the same as boxes, huge boxes.  

When I bought my first computer, what I did was buy a 3D software. As you can guess, what I drew using the 3D software was a box. I wonder why I don't get tired of making boxes?

So, I like packing types of puzzles as well. Usually, having the skill of solving puzzles is not useful for our daily lives but I think packing puzzle skills might be useful when you pack a suitcase or pack your belongings when you move.
Unfortunately, I don't have too many opportunities to pack a suitcase, but I enjoy puzzles involving boxes.
