I totally get why people like terrariums. They are pretty, they let you try your hand at green thumbin', they bring fresh greenery into your home and all the clean air, chlorophyll-y benefits that come with that.
The thing is, I don't really care about that. I'm a smoker, so air quality is obviously not my highest concern. Plus, I'm a master at killing plants. When I bring plants home, it's pretty much the same fate as when people with pet snakes bring home mice. I just want a cute little ball of green crap to make people fake-impressed with my ability to cultivate (sham) ecosystems.
And to have a place to put all these tiny animals I bought for fifty cents at Family Thrift:
I will give a special prize to anyone who knows what the fuck that grey thing with the weird eyes and bloody chest is...
Anyways, you just layer it up like a taco dip and added some animals. Voila, you now have something to put into your apartment to trick visitors into thinking you are a much more responsible and capable adult than you actually are.
