Acorn

I slept  a bit better last night thankfully, though still taking painkillers to get me through the day which followed the usual format - walk, work, walk, work.  It was another really really busy day, which helped to take my mind off my aches and pains, though by the end of the day I felt quite worn out. 
 
BB got a good mark for his physics test, so was pleased, as he thinks he can’t do physics.  He clearly can given the marks he has had recently.  Later he had a Zoom call to plan his next DoE expedition.
 
I baked some biscuits.
 
There a couple of nearby oak trees which are covered in acorns.
