I've made a couple of new friends recently (past 3-6 months) - a couple of really nice guys who've know each other a long time. We arranged and have been out walking and scrambling in the mountains a couple of times and are planning more trips - these are things I love to do and I really enjoy the fact that we're doing this. I want to explain to them that I am sometimes preoccupied with my own thoughts, situation, problems, etc and that I don't want to e-mail much (hardly at all) or to e-mail back straight away - I don't like wasting time on the internet which is why I don't post that prolifically anywhere about anything. It must seem rude, forgetful or inconsiderate sometimes but often I just don't feel ready to reply or to be more chatty or upbeat than I really feel - I like to be left along for long periods of time without feeling like I need to "keep in touch" - I want to be able to say this without getting myself excluded from this newly formed friendship group - I'm just not sure how to say or explain this to them. Your thoughts?
