"But, but, I wanted to work on my project! :'o" (Joke ;P )
First things first, this is the first time I've heard @TheEighthHour do one of the British accents, and I have to say, he does a jolly good job there, no complaints there!
This is a very interesting idea, and I'd love to see more!
Personally, if an old friend sent me a message out of the blue, I would open the message, not delete it, out of curiosity.
If insults and pain was the content the message, I would be disappointed in the sender, then delete it swiftly, and move on with my life. If good feelings, like the potential to rekindle the friendship, was in the message, I'd take an awknowledging action towards them.
