I brushed my teeth at 3am and drank a can of coca cola at 4am.
Why did you brush your teeth at 3am and drink a can of coca cola at 4am?
I got really thirsty and all I could find was soda.
The soda probably wasn't a good idea, but it is good that you brushed your teeth. If you don't take care of your teeth you'll get cavities.
I'm thankful for the reminder. I'll try to brush my teeth in the afternoon or evening.
You can brush your teeth whenever you like and it is a good thing to do to take care of yourself.
