Lisette - The answer to this question completely correlates to: where I am in my cycle, how much sleep I have had the night before, how lazy my husband/lover-man has been, and whether I have exercised recently. If I am tired, have PMS, have been cleaning the house all week to no avail and haven't exercised, the world is just an awful, awful place and everyone is out to get me. However if I have been for a bouncy run while the lover-man vacuums the floor and deals with the children, then all is well. Life is good! Such a blessing!
If I ever watched the evening news though, (which, in our home is just known as "The Bad News") I think I would definitely be a pessimist!
