(I’m barely exaggerating for real, the 2am text really happened more than once)
I have a friend and former (I guess) bandmate who would text any time of day or night about whatever random thoughts he was having, and to make it worse, he never completes a thought in one text. Minimum of three, spread out over ten minutes or more. If you get one text from him, buckle up, there are several more being typed up as you read the first one and they'll be on the way shortly.
This prompted me to learn a bit more about the capabilities of my smart phone, such as how to turn off all message alerts during sleeping hours, while leaving the voice phone ringtone on in case I get an emergency call. Problem solved. Mostly.
