Open System
A system that exchanges matter, energy, information, or influence with its environment—it's open to outside input, open to change, open to learning. Open systems are the default in nature: ecosystems exchange nutrients, economies exchange goods, relationships exchange feelings. Open systems can adapt, evolve, and surprise you, which is both their strength (they can improve) and their challenge (they're unpredictable). Open systems are what therapists work with, what managers struggle with, and what anyone in a relationship is definitely dealing with. The opposite of an open system is a closed system, which is either a very simple machine or a person who's decided never to change.
The Urban Dictionary Mug
Istgd imma force my mum to buy this idek hw i find out but this shit looks fucking fire

Perfect coffee cup for a hockey fan. Great conversation starter.
Perfect gift! My husband loved it. So funny and clever!
Great mug… got one for my girlfriend… instant sex
As always, these are well made mugs that stand up to most anything. And they make perfect gifts (in this case for dirty-minded members of a wedding party). I’m extremely pleased.
Is a great mug that I purchased as a gag gift for a coworker. You know the one who also as interesting words/phrases that only urban dictionary can explain. Great as a coffee mug and better as conversation piece!
👍

The mug exceeded my expectations. Really excellent quality and build
Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
Great gift!
A little spendy, but worth it.
My wife kept talking about "ways out" being a Denver version of "psych" and she was right, so I got her this once I found it on UD. She loved it!
It's a great mug, will reccomend to family members my grandma gave me this mug for christmas and it was by far the best gift i got.
It arrived three weeks after ordering but given the holiday rush and inability of shipping to keep on schedule arrived late but was perfect little gift from me to my wife for her morning coffee with her "nickname" on the mug.
I liked the photo on your website and so I ordered the mug. You sent it right away, and it looks great!
Arrived carefully packaged

me and the boys when i get vodka mug
I ordered 3 of your mugs, with different names on them. There was a typo in the information about the name on the back of each of the mugs. This wasn’t a dealbreaker because the people who received them liked them. However, it would be nice if somebody who has basic proficiency in spelling English words could proofread the script for all of your names before they’re prepared.
Arrived on time. Great packaging. Communication with vendor was top-notch. High quality item.

I love it! Thanks! So
