Ricardo sent him the Minesweeper problem.

Wasn't early to the meeting.  Showed up at 13:02 

Console application in C#, limited GUI

Seems familiar with Visual Studio.  Able to explain his basic plan to get going: two models (Cell and Board), one service to calculated neighboring cells.

Interesting choice: adding "NeighborCount" on the cell model--should the cell model know about its neighbors?

IN progress: ahs not initialized the Board property yet--how will he discover this?
	Got NRE when he ran this. easily found that he missed initializing 

Questions:
1. Can you GridSize everywhere to avoid errors?
2. Does each Cell really need to know it's neighbor mine count? Or is that something the board knows about?
3. Instead of a `(Row, Column)` comment, is there another way we could label the values?
4. Is there a way to calculate the coordinates of the surrounding cells without statically constructing a list of offset pairs?
5. You iterate through all cells in the board multiple times.  Can you extract that logic to reuse wherever needed instead of copying it?

Nits:
1. Property, field and variable naming not consistent

Notes:
1. Using `Random` to fill 10 mines into the board, knows basics of `Random` API.
2. Speaks English _very_ well
3. Did not run the program early to see if there were errors
4. Found a bug he wrote in column and row check before executing program by thinking about it logically and visualizing the board.
5. Has a bug using `.Length` of a multi-dimensional array!  Will be x * y and not x as he's hoping. He figured it out without any prompting from me and used `GridSize` in the check instead.
