This happens more and more. Either via text or via FB message, both of which show as 'read' when they've been read by the recipient.
In the past few days someone has text me asking for another friend's phone number. I replied with the number, she read it and didn't acknowledge my message.
A mum from the school sent me a FB message asking me what time and venue another child's party was this weekend. Again, I replied with the information, which she read but didn't acknowledge or thank me for.
At the beginning of the week a colleague text me asking for some help with her work (we job share, she is fairly new, boss was in a meeting, she needed quick answers as to how to do something). I sent a lengthy, helpful text back and again, no acknowledgement or reply even though she read it!
AIBU to think that this is fucking rude?
