You know you have items in your home you will never use again. These...just in case... things like extra blankets, pillows, towels, etc. They NEVER see the light of day and just take up space.
Whether it was watching those effected by Hurricane Harvey who have just lost EVERYTHING, or just knowing plenty of people go without... clean out and donate those items.
You don't need them... but others do.
Reach out to the Red Cross if you'd like to donate.
