Do you like gardening? Or growing plants in vases?
In order to deal with stress I found out that collecting and cultivating cacti is one hell of a good therapy.
I'm something of a Buddhist, I love and respect all kinds of life, and though I do love dogs and animals in general, I also like plants a lot. And now that I'm living in an apartment, I gotta keep things real. Cacti are forgiving, enduring forms of life. If well kept, they'll be good pets/bonsais.
Right now I own a few species, a Mexican Asiento de Suegra (barrel cactus), a couple of Mandacarus (a Brazilian cactus) and recently bought a vase with a nice Texan barbed wire cactus...
Show your garden or your vases, if you got 'em.
