Bonsai

"This is one of my father's bonsai plants.
My father has some bonsais and looks at them every day and smiles.
My father said that 'I think that it is good that bonsai plants have an unsymmetrical shape because dissymmetry is more natural than symmetry.
However, to be honest, I can't understand what is good about Bonsai at all.
Because I am more interested in food than in plants!"

The above is past of an email I got from Ms. Y. What do you think about Bonsai? Do you like them? Do you have any?
I think Bonsai are really cool. I do not have any Bonsai plants, but I would like to get one some day. Actually, since about two years ago, I am really into plants! I have about 10~15 plants in my house or on the balcony. But in the winter, it is really hard to take care of them. This winter, because it is so cold, I, and the plants, are struggling. Do you have any advice on how to take care of house plants during the winter? If you do, please let me know. I am all ears!!
