This isn't a 'biggie', but along the lines of stupid things that dh's & dc's do ...
Dd's school write a letter to a grandparent, asking them what life was like when THEY were young. Grandparent then writes a reply. We chose MIL as the grandparent to be 'honoured' with this task. She has written a lovely reply BUT, she has chosen a font which is so curly, like real handwriting, that I am struggling to make out all the words. dd is 6, and is meant to read the letter out in class. I am going to have to change the font, aren't I, and tactfully ask MIL to use a boring font next time.
Surely, MIL should have thought of this, she does when she writes postcards, or AIBU to expect her to make the letter legible?
