"Treat them just like any other person with basic kindness, respect, and normal conversation."

Christian:

"If you are physically with someone right now and feel unsafe or threatened, please leave the location or call emergency services immediately. If you mean you are spending quiet time alone or feeling lonely as a believer, many people experience this reflection in their faith."

Islamic person:

"Being alone with a Muslim person is a normal interaction guided by standard human courtesy, mutual respect, and basic kindness."
