Bachelor's decoration

Today was our eldest son M.'s birthday. 28 years ago, also a Sunday, it was freezing cold. Now we have 6°C and a bit of sunshine.
We visited M. in his flat some 60km away from our place. He works as event manager, although due to Corona the amount of work went terribly down, so he is in 50% short-time work. At least with 90% pay.
We had a cosy afternoon and early evening, just Hanulli, Teba, M. and me. M. is the only other household we meet.
Although M. is a bachelor, his flat is nicely decorated for Christmas. The title of this blip is hence misguiding, on purpose of course.
