I think it's rude so I have added this to my profile

I think it is rude not to pick up chats from where we left off. otherwise it's a waste of time.

And this is the reason why.

I think it's rude and shallow of people not to acknowledge your comments while having PM chats. I'm finding half the things I say to some people are a complete waste of time. I don't do this to people as I was not raised to be this way and I'm not going to start because I've joined a social media site. So if you're that way inclined, don't bother making contact, simple.
