I call my daughters school to find out what clothing items are needed. The school has a clothing closet for children that don't have enough clothes - if I don't have what they need, I go to our local thrift store and pick some up, wash them and send them the next day.
I also let people behind me go in front of me to checkout if they have a few items.
I open and hold the doors for older people (to me that is common courtesy) but unfortunately many others don't see it that way.
What a great topic to post here - it will open my eyes to other things that I could be doing :)
thank you
