Are you one of those who has rude friends who call or text you in the middle of the night

I did have. They got the picture after I growled "Don't you OWN a goddamned clock?" and hung up before they got a word in.

I put my phone on "Do Not Disturb" mode at night so it will not go off if I get a call or text but it could still be quickly used in an emergency. 

No, I don't.  For one thing, I don't have the text feature on my flip phone activated and for another, I don't turn on that phone unless I want to make a call.  I have a landline in the house if my phone rings in the middle of the night, I know it's either a wrong number or something serious. 

No one would call me in the middle of the night unless it was an emergency.
I don't have my cell phone charged and I don't text. The ringer in my bed room is off, so I wouldn't hear it in the other room  anyway if I am sleeping. So if someone has an emergency, they would be better off calling someone else LOL.

Nobody I know would be so rude.

If my 'phone rings in the middle of the night then it will be a for a genuine, serious reason; but I may not hear it anyway as it would be my land-line 'phone, downstairs. My portable 'phone is Off at night... and for much of the rest of the time too, for which my sisters have occasionally ticked me off!
