Keep your head down, say nothing and live out your last days in oblivious harmony, if you've been generous and kind to your thai neighbours around you they'll look after you.
Met several foreigners (I won't say where) who in their advanced years just live a low key under the radar existence, too old to move on and too brain fogged to deal with the beaurocracy, mai pen rai 🙏
I don't think they're going to penalise you because you've had the misfortune of your partner passing away..........unless of cause you ahem, 'helped' her on her way....🧐 😜
I wouldn't worry too much mate, it's not a dictatorship , though I did once here of a fella who had a bar in Pattaya who was closed down for changing a cd ! Not sure how true but think it was more to do with local mafia politics.....
Make a point of getting to know the local police chief and invite him round for a few whiskies and air your concerns, he'll probably laugh ! Mai pen rai 🙏
