A plague on public transport

We are actually big fans of public transport, but it unfortunately means contact with the public.  To cap our bloody awful experiences last week, we have both come down with nasty colds, and have had to cancel social engagements and a day at the hobby.  To take five buses and four trains in the space of two days at this time of year is risky, I guess.  Just as well we have no plans to entertain at Christmas - we shall have a few quiet Darby & Darby days at home.
