So you're texting a friend. So you've been doing it for the last 20 minutes. So you are getting all the latest gossip about their little life. So you sent them another message and they didn't reply. So they still haven't replied 2 days later.
What does this mean?
Do they not want to talk to you anymore? Have you suddenly grown boring to them? Have they been irritated by something you said?
Your curiosity has peaked, you simply must know why they haven't got back to you. So how do you ask them, without being rude?
If you blurt out "Why didn't you reply?" or even more abruptly demand "Well?" your friend may not stay your friend for very long. The case may unravel to be that the text never arrived, and the blame falls upon your service provider.
So, after 2 days worth of deliberation and erratic pondering, you've formulated the perfect text message that covers all possibilities, "Did you get my text?".
If the answer is no, then you can resend the unanswered text.
If the answer is yes, then they probably meant to get back to you but ultimately didn't.
They could also ignore this one as well...
It may however, be an innocent mistake like their credit has expired or they have broken their phone.
If it was any of the more 'acceptable' circumstances then surely they would have endeavored to contact you another way. (Unless the conditions were so extraordinary!)
Which begs the question, is the unresponsive 'friend' really worth the effort?
