Would you prefer?
That someone tell you the truth if you just don't click or remain silent and pretend that you don't exist?
Personally I would rather have someone tell me that we just don't click as friends. Ignoring is much more hurtful and rude. Besides if there were a reason, it would be something I can work on.
This is just something I have noticed in this so called technology age. It appears people don't have to deal with people face to face anymore so it is okay to be rude. This happens in personal as well as work life. Saddens me that the internet has done this because it is so much easier to discard people's feelings through the internet.
Just an observation.
