Nearly ready to leave for Paris on Sunday

I have got all my Skiing and other "essential" stuff into my check-in and cabin bags. 20kg in the hole and 12kg in the cabin. Just enough to squeeze it all in. Lots of guide books to read on the flight and my new android Phone to play with and listen to my French lessons. My Ski gear takes most of the space as does my electronic toys and all their spare batteries and memory chips, chargers, cables etc. I feel organised and ready, I even have the ticket for train from CDG airport to my friend Fritz's home. (Fritz sent me the ticket). I'll try and relax for the next 2 day. I hate that last minute rush. I have this feeling that there is something very important that I have forgotten.
