Utter as in uttering, usually goes along with forgery, but not necessarily. Uttering a forged instrument is the act of presenting for payment a document (check) that is not the property of the presenter. A forged money order, busness or cashiers check applies as well. Generally a person convicted of this offense is caught writing someone elses personal checks without ther approval.
It is starting to get dark between 7 and 7:30, right now (remember, that's really 6 - 6:30, starndard time). It being early September now, that means it will be starting to get dark by 7PM, for all intents and purposes, and will be essentially completely dark by 8PM.
So aim to be in your bed with the lights out between 9:30 P.M. and 10:30 P.M. If you are not used to getting to bed this early, move your bedtime up by 30 minutes every week until you are in bed by 10:30 P.M. For example, if you usually watch television until midnight, try turning off the TV by 11:30 for a week.
