Working whilst traveling

Today I traveled up north to Groningen to visit Pippa. Only after a self test to check if I was still negative fir Covid (school feels like a battlefield at the moment, with a lot of teachers in isolation and only the odd grade left in school). Today and tomorrow are off school for me (jey to being a part-time employee). However, IB DP1 exams are this week, so I am markings exams on the train.
