It's so sad that security these days keeps out people who really can do good things. So many elders are lonely and forgotten. Nursing home personnel know that, but they have to have rules. They are responsible if anything happens to the elder.   Perhaps you could go through a church or other religious organization. They may have contact lists for elders who want company or caregivers who need respite. A local senior center may be a place to get leads, also. Conversation with seniors there could bring some ideas. I hope you can find someone to help, as people need your kind of care. Blessings, Carol
