Good point. Having to share a workspace with someone else that doesn’t have the same outlook that you do can be quite enlightening when evaluating your own needs.
A brother and a sister living under the same roof might seem challenging enough. But try putting a minimalist graphic designer with a clutter-loving crafter and see what happens. For me, being that sister, it was quite a struggle. Although, I must say, living in that environment taught me a lot about what I actually needed in a workspace.
