"Do you mean to run by again?" the girl asked in surprise.
"I was thinking," I answered.
"And yesterday you were thinking so hard that you did not even hear me call after you!--How you look!" she cried in sudden apprehension.
"I do not know of anything. How do I?"
"Worn out! Terribly! Have you been revelling all night?"
"Revelling!" I murmured with a smile, and relapsed into my revery.
"But what is the matter with you? Erwin!"
"I don't sleep well."
"Are you writing verses again all night long?"
I shook my head.
