What is at the absolute bottom of your knowledge pile?

[Jennasis]

Math and sports.

 

[fly girl]

Anything on the working parts of cars. I appreciate it, I just don't know the mechanics of it all.

Physics. I did not enjoy that science class.

 

[Praying Colonel]

Knitting and sewing. DW is great at both; I don't know how to sew on a button.
