I don’t claim to have a lot of peeves, but here’s one that certainly tops my list… when pens or markers are left uncapped or clicked open. Granted, ink isn’t meant to last forever, but in my opinion the premature death of a good writing utensil is simply inexcusable. If you are using a pen or marker and you choose not to cap it or click it shut you could just as well skip putting it back in the drawer or bin and toss it directly into the trash.
A lot of my pen peeve frustration stems from having my favorite pens/markers as a kid used by other family members and treated in this way. While I couldn’t break my entire family of this habit I think I’ve got my kids pretty well-trained. With any luck, my drawing pens will live a long, full life making their mark for many more months.
