I am a creature of habit. My junior year in HS I took 2nd year chem, which was two periods long, 4th and 5th. We got dispensation from the principal to leave after 5th if we had no other classes (seniors could anyway, but not juniors). I had lunch every day at McDs. My senior year I had no 6th period class and had lunch every day at Burger King. I got a Whopper, a large orange, and fries, for 99 cents. The lady who worked there every day, by herself, would see me pull into the lot and have my order ready when I got to the counter.
For breakfast, my Mom always fixed 4 fried eggs, grits, toast, milk and OJ. I would not gain an ounce.
These days we usually have leftovers from dinner that I heat up for lunch, today it was one taco and some cabbage soup (which I made, it's quite good).
