@StillCoughingandLaughing Well said! And that goes to a few others too, who said there are so many bloody rude, inconsiderate, entitled twonks. Making it the recipients fault for being disturbed, for 'not having their phone on silent' at 4am, is rude, entitled, and borderline narcissistic.
And SERIOUSLY, what the actual FUCK are you texting people at 4am for ANYWAY? As a pp said, if you know the person is not going to be up til after 7am (ya know like MOST people!) then why not just wait til then to bloody send it? 
Oh and by the way, I have several sets of friends and relatives who live in different timezones. NZ, Eastern Canada, Uganda, USA, and Cambodia.
Yet they ALL have the intelligence, common courtesy, and consideration to message/ring/text at a time when they know we will be awake. JUST as I do with them
Shame some people on here don't have the same degree of emotional intelligence, maturity, common sense, and thought for someone other than themselves.
This 'I will do what the fuck I want, so deal with it' attitude from a few posters on here is revolting and ugly. As I said, you'd be blocked from my phone in the blink of an eye if you messaged ME at 4am. (Probably blocked from my life as well, as I have no time for people like you.)
