The feeling of "lonliness" when solo tramping

I almost never tramp on my own but I'm sure I would feel like you do if I did. Sometimes I wonder how the cat's getting on though most of the time I never give her a thought. I am a dreadful ruminater when I tramp though and yes, it's annoying and interrupting that connection with the present (being in the moment or mindful) but it's also quite tiring. Rumination is even stronger when I do track work as it can be quite repetitive and mechanical. I think if one was totally engaged because the tramping was very challenging e.g. route-finding and then tied with tasks in the evening to meet one's needs, one might not feel so lonely.
