Challenge #8

Earlier this week when the lady came in with her "ancient" laptop,

I was trying to explain to her how she could free up some space on her computer (because it didn't hold very much) she said "You're speaking Greek to me." I've never heard that expression before, but I instantly knew what it meant.

Here is the definition:

All Greek to me - Meaningless and incomprehensible like someone who cannot read, speak, or understand any of the Greek language would be.
