In our house...family of nine:
No long distance on lanlines b/c we have cell phones
No eating out b/c too expensive for a big family....eating at home is better.
No sodas or coffee 4 me....just plain water,kool aid
No use of oven/stove during the summer...we grill all the time or microwave foods and left overs, use of crock pot.
No use of washing machine/dryer after 9 pm...so that why I am up still..washing clothes.
No abuse on the a/c thermostats...meaning we can not touch it. We have ceiling fans running in the house
No excessive/impluse shopping...meaning buy what we use/need in the house. Buy what is on sale, use coupons when possible.
No candy, gum in the house...bad for kids teeth. Man...dental bills...are crazy in this house.
