Keeping in mind that 'friends' could mean family. I live with my adult Thai son, his Thai wife, their 4 kids/my grandchildren.
My Thai wife deceased some years back, she was a dr. of medicine.
My days are consumed with conversations with my son (speaks perfect Thai and perfect English), and his wonderful Thai wife (perfect Thai, good English). We discuss family matters / family needs, coming school events and fees etc., etc. I made it clear years back I was very willing to join family discussions but ultimately I wanted my son and his wife to make all decisions. It works.
And lots of contact with my grandchilden. My Thai language is prettty good but at the request of my son and his wife I never speak Thai with my grandkids, so that they have English immersion every day and it works. And we have a lot of fun. I take them to the supermarket, I give each grandchild a task to find something and come back to me and put the item in the shopping cart. e. g. 'one big green bag of sliced bread', or '2 lt of milk with dark blue top' or 'three chicken breasts', or '2 big cans of chopped tomatoes' or 'check the price today of dark grapes' in the fruit section, or 'what's the brand name of the cheapest big block of soda water and the price'.
The kids never frightened by their tasks, I never get annoyed by a mistake, just use it as an opportunity to discuss further (more English immersion).
In my village there's 5 older farang men incl. me. We meet once or twice each week at one of the houses for cofffe / a beer. We banned discussions on Thai or US politics.
As above, I'm not lonely.
