The message
from Owain contains these words:

I developed a habit of getting out of bed about the time my parents
finished their after-dinner sherry so I was allowed to drain the
glasses. :-)

In the late 60s when I was having parties as a smallish boy mum used to
make rather strong sherry trifles. Apparently the guests were very
subdued and appeared extremely worn out by the time they were collected.
Other parents assumed they'd been very busy...
