so I've just been told by a friend that she lost someone who she knew for over 5 years

I also knew this person and he was bossy, he was rude, and he spent most of his life putting us down or telling us he was better than us

now she's emailing me.. oh he's gone, I'm so upset, I'm so devistated what do I do- nad part of me is thinking what?. but when he was alive he was a nasty peace of work

how can I show support to her because honestly A- I don't know how she can miss this guy, and B- I certainly don't feel anything
