With the gas prices being close to $4.00 a gallon (some states already there) I have trouble keeping my tank half full or even a quarter full.  Actually, I consider it half empty or closer to three quarters empty;  I guess making me a gas tank pessimist.   Normally, I try to see the good in everything but when I put $20 in my tank it only registers a quarter of a tank.  That $20 used to give me a half tank.  That quarter of a tank seems to disappear fast.  I drive down the street and all of sudden I have an eighth of tank.  I drive a jeep so it’s not a gas hog.  It just seems that last quarter goes faster than the first quarter when you fill up your tank.  Recently, I was laid off my job, so it’s been a long time since I filled up my tank.  I can’t afford to.  Sometimes I will apply the breaks a little harder and that brings my gas back up to a quarter.  It’s a psychological thing; it helps when you’re broke.
