Yes, we’ve had to deal with students from time to time. More understandable as they’re so much younger. What often worked for us, if they were outside, was to say their voices travel at night, and we can hear every word. That seemed to embarrass them, and they always stopped. Nowadays, they’re always plugged into something. We don’t hear much at all.
Whether it would work for this man, I don’t know. His generation were the first age group we started getting students in our area, and they tended to be noisier. This was 15 years ago. For the last 10 years or so, it’s been getting much quieter.
Somehow, you need to make him feel silly, too old for this, embarrass him. Of course, the parents are a good first step.
In our first house we had awful neighbours, constant shouting, arguing and loud, long parties every weekend. We went to work abroad and deliberately rented our house to a group of male students, expecting them to have a similar loud lifestyle! Sadly, another neighbour told us they were lovely lads, they only saw them at the weekend when they were cutting our grass!
