These ones don't like too much water and can't stand much light. Yours suffer from the light. I have the total green ones and they do better. Just remove the brown leaves and see if it still has watee and earth (perhaps roits only). It might like a different view better or a less toxic one. Plants inside also suffer if you painted the walls. Lucky you, you have a few more weeks added to life it's worth a beauty treatment for the plant!

These are the only plants surviving the cold and you can bring them back alive after 4-6 weeks without water. It intrigues me since I was at primary school where a plant was left behind during summer holidays and no one watered it. I did as school started (I noticed it) although it looked dead.
