how to cope with social pressure when fasting?

Hi,
I'm on my second day of fasting and I find it very hard to cope with the social contraints it imply. In my country everythig is around food so people do have seated lunches everyday and so on... what to do then? join and just stare at the food ? I have been at home reading and watching tv and all but I feel time is passing slow and am a little down,

any suggestions on how to cope with this?
