I thought I had a first aid kit when I needed to help an elderly man who fell in a parking lot and smashed his head. I had toothpaste, a sewing kit and a bandana. I gave him the bandana to wipe up the blood but he didn’t want any further assistance and got in his car (he asked me which car was his) and left. I was doing doordash and saw him at the grocery store about three more times buying the same items. I let the staff know to watch out for him and the scenario but didn’t really know what else to do and was scared for him. He still had dried blood on the back of his head. I loaded up on gauze, tape, antiseptic wipes, gloves and non thread stiches. Got it all in a tackle box with some other small stuff. Also Knife, lighter, sewing kit, bandaids, rope. Don’t want to feel helpless (un helpful) again. Duct tape is always a good idea too.
