Took the girls to an old Abids stationery shop for ink pens. Both have blue fingers now

Wanted to show them the kind of shop I bought my school pens from. Same glass counter, same elderly uncle behind it, a bottle of ink for less than a samosa. They each picked a pen and filled it themselves at the dining table. Two days later: blue thumbs, one blue school sock, and a blue mark on the sofa my partner hasn't found yet. They've written more by hand in two days than in all of May though 🤷
