Trying not to kill this

A few weeks ago I saw this little guy at Home Depot and thought its bumpy leaves were weird and cool. It was in a box of plants marked "Exotic Angel Plants®" that don't seem to require much light, so they're good options for offices, tables, desks, etc. So for a couple dollars, I had to give one a try. This plant is a Pilea originating in Vietnam. And according to its label, "Your home deserves them...™" This plant also promises to "Purify air, enhance décor, and calm senses." Wow. I thought I'd been feeling calmer lately. :)
