Any tips for a soon-to-be college student clutterer who has to live with her (also a clutterer) grandmother for two years? I have various totes filled with things I don't need, so I really don't want to fall back into the habit of buying things I don't need. My grandmother is one of those people who refuses to let go of anything, even food, despite it having no use, doesn't work anymore, etc. I really don't want that affecting my progress. What should I do?
