Taking the rest of the week off, and taking a ride with a different
CFI at a different school is an excellent idea. As far as "the DE
wants denterline landings...." know what? There are lots of DEs
out there. Your school may use one DE to the exclusion of others.

I took a 4 month break from lessons when I had to go out of town
on business for an extended time. Of course while out of town
I was taking lessons at that location. When I came back, I never
went back to my original school. Life was much better, and I learned
from a much better CFI -- one who wasn't intent on getting a
"real flying job" instead of teaching.
