When someone comes and rips the paper in half

Or how about when charcoal gets on your hands and you don't notice. So you walk around all day with charcoal on your face.

Messing up with paints or ink.

Breaking your program

When you lose all interest in working on it halfway through. So it sits in the corner of your room or on the laptop buried deep within the files.

Still haven't found the pen :'(

did you lose the pen to your tablet?

yep

Try to order your pen from the website of the company of the tablet you got.

Surely they sell those. Depending on what kind of tablet you have.

When noodle arms are all I can do.

When noodle arms are what i can't do.

when those noodle arms are the eyes of my character *shudders*
I might get a Wacom one for Christmas this one is cheap.

Or when everything is just not working right for some reason.

when pressure doesn't work right and you realize your using a mouse.

when the pen nub breaks

A pet peeve of mine is forgetting what im drawing while i draw >~>

Oh how about when you want to draw something but end up drawing something else. So you don't feel satisfied and so you keep trying to draw the same thing.

How about when you draw an eye and it looks like a mouth so your drawing has mouth eyes...

Or when you draw something but your computer shuts down or you accidentally closes and you've been working on it for a few hours and you didn't save.

Or when the whole computer dies for good. man that sucks

when the power goes out while you are drawing.

when The thing you draw is like a crude replica of you.

when your siblings steal your tablet.

when your tablet is missing it's buttons

when you give up
