4 hours discussion with C Fu today

Tomorrow is the official start date of the project, so today had a 4 hours discussion with C FU to finalize most of the details.   The difficult discussion is I need to finalize most of my 起居飲食嘅地方同一切壞習慣, so that where to place the lights and the electricity suckets.  Weird experience!   C FU understsands very well that I have firm requirement in the bathroom setup, so we have spent 30mins to "deliberate" a 1.5" wall !!   within the next 2 days, I need to get back to him on below :

1) where is the Sofa will be placed?
2) can I settle the bath area to be 1.5" "shorter?
3) floor LED lights - needed?
4) bathroom door - need lock ?
5) how to place the floor tile - vertical or horizontal ?
6) windows - redo?

Aiyo .... a lot of things need to make decision!!   start to get terrified!
