Back when my college switched from chalkboards to whiteboards, but before they put projectors in the classrooms (so there was no other way of displaying information to the class), I could easily go through a marker a day. (A day of several math classes, each of which involved lots of writing and working out problems on the board.)
Amen.
Let’s you and him fight.
Dry erase doesn’t on smart boards. And curse the person who put them within reach of it…
Markers at dawn! The grassy area near the sciences building. 
In all seriousness, I don’t store them nose down anymore. Not since a few unfortunate, ahem, oozing incidents.
The Librarian, cool it off. Personal insults are not allowed in this forum.
No warning issued.
If you’re going to ooze I’m not going to touch you much less fight you.
On edit: Also, chicks dig dry eraser scars. Makes you look tough.
Sorry, I had some frustration irl spill over my keyboard.
Yup. The light in the choir loft is VERY yellow! Great call! I am also developing a cataract in my left eye, which puts yellow circles and/or rainbow circles around glaring lights (car headlights at night, in particular).
Time to get back to the eye doctor, I think 
When that happens I scribble over them with a marker. Helps loosen up the ink so you can erase it.
Hey, I have the solution for you.
The fountain pen brand Noodler’s makes dry erase ink called “Bluerase”. I believe it even comes with a free marker pen at most retailers. Otherwise, you can buy one from a brand called Platinum for like $3.
Ditch the pointless disposables and go with refillable markers, I say.
