If I met someone through a shared activity such as hiking or someone at work and I found that we had similar interests, I would invite the person to my home for lunch on our day off.
If they drank alcoholic beverages, I would off them a beer or some wine. If they didn't, I would offer coffee, tea, soda or water.
For lunch I would have a tuna salad which I made from "scratch." Also, I would have two platters of cold food. On one there would be black and green olives and marinated artichoke hearts surrounded by assorted old cuts. On the other platter, there would be grapes in the middle surrounded by assorted cheeses. Dessert would be strawberry pie and a beverage.
After lunch we might play cards or scrabble or maybe just visit.
The above would be before I had a stroke. Now, if someone knocks on my for, I'll say, "come in." Usually there is no response. If they do come in, they refuse to sit down saying that they don't have time. One person I invited said she preferred to be alone. Of course, she has a son who visits her. Now if someone comes they would have to help themselves to food and drink which they usually refuse. Things change when you become handicapped.
