preparation for the cold weather

okok, expecting the cold weather to limit my twice-a-week trips to the supermarket, hence i have to prepare myself...

water... checked (30litres of them- i can even bathe in mineral H2O)
food.... checked (lots of junk food + pasta + meat + vegetables+ 2 litres of milk)

hmmm... i can afford to get stranded in the house for a few days... =)
