I wrap the safety belt of the cart around my purse several times. I have taken most of my credit cards out of my purse and leave them at home. NOW I try to remember to put my car keys in my pocket. Several months ago I loaded groceries into trunk of car and had put my purse in ahead of bags and slammed the trunk ,Purse, keys and cell phone all locked up. Prayers DO work...... a sweet young lady came along and said "you look like you need a friend" I told her my problem and she brought me home to get another set of keys and then took me back to the store. I live less than half a mile from the store and considered walking home but knew my knees and feet wouldn't carry me. There are some good people in this world even today.
