Man it's crap when this happened,
A good friend of mine from work died around 4 years ago now (I lived in the flat above him too). I know what you mean about the empty space - and you end up seeing their name all over the place on documents that have been uploaded to various shared spaces.
For reasons I won't go into, that death was totally avoidable had he not been in total denial about being ill for so long, such a waste!
it is, isn't it..... must be hard realizing his passing had been avoidable... darn... Thanks !!!
