There are a few valid reasons to text or call someone at 1:25AM.

Reason #1 "Hey Ed, I'm drunk and really horny. What's your buzzer number again?"
Perfectly valid reason.

Reason #2 "Hey Ed, I accidentally killed a hooker and I need your help to hide the body"
Not a text/phone call I'd ever wanna read/hear, but depending on how close we are I'm either there for you or I'm calling the police immediately. Be very sure you're my best friend before before making this call/sending this message.

Reason #3 "Hey Ed, (person really close to you) is in the hospital and they don't have very long"
I'm on my way.

Reason #4 "Holy shit! Just got word pirates are gonna invade English Bay! You need to get outta there now!"
Thank You.

Reason #5 "Dude, the zombie apocalypse is happening right now and they're heading for the West End!"
Once again, thank you.

I'm sure there are other reasons, but I doubt it. If it can wait till tomorrow, THEN IT CAN FUCKING WAIT TIL TOMORROW!!!

And I get it, sometimes mistakes are made. A simple, "Sorry, didn't know you were sleeping/trying to sleep" or "Shit, didn't realize what time it was" or -- best of all -- NOTHING would suffice. Nothing's the best one cause if I didn't get a reply from my "DO YOU FUCKING KNOW WHAT TIME IT IS?!" I'll feel bad in the morning, send you an apology and possibly buy you some sort of present or meal.

But if I get, "You really need to learn to turn your phone off" I'm gonna be fuming all night, not get a wink of sleep, be a super peach to everyone I have to deal with during my 12 hour shift, and write a passive aggressive entry into a blog I never use anymore but I needed more than 140 characters to get this off my chest.
