I get lonely quite often, but at the same time I prefer to be on my own. It's a hard mix to get right haha. I actually get annoyed when people text me or call me, because it means I'm forced into replying and I may already have plans laid out which are now going to be put on hold.

I understand what you mean about rubbish replies though. If I am in the mood for conversation, which is rare, I get pretty upset when people don't ask any questions in return. I find it very hard to keep a conversation going because I'm never sure what to say next, so if they don't ask questions it all just frizzles out very quickly and then I usually get blamed for 'not seeming interested', even though from my point of view they are the one who lost interest.
