Bambu, I agree with you about having strangers in my home, I do not allow any strangers in my home. Once I let a stranger use my restroom and he stole a bottle of Drakkar Noir worth $80 and so now I will not even allow a stranger to use my restroom.
When I lived in Malibu in a family home on the beach with the ex-wife of a Doctor and their two daughters, and also the daughter of a Chinese general lived there, and a research scientist who worked on artificial joints such as hips and knees, etc, I had a great Character Reference in order to get into the beach house, I had Roy Rogers and Dale Evans as my Character Reference, and the Lady who owned the house was a huge fan of Roy and Dale. Plus, I had a college degree, and I attended the American Academy of Dramatic Arts, so she could tell that I am a good guy.
But, I agree with you when it comes to inviting people into my home, I do not allow strangers in my home.
The best way to help the refugees from Ukraine is to have group homes full of beds and ran by ex-military guys.
Salute,
Tony V.
