like EJCC said, i go back and forth. i'll get really lazy feeling, and then suddenly get bursts of energy where i feel like i gotta move around. i also feel this like great sense of opportunity when i'm alone for a long time. like i have all this glorious time to do literally whatever i want with. it's overwhelming, and i often end up with a lot of half-started projects. more often than not, i just get really into learning about something online, and go down rabbit holes like that. also, loud music. every time.
yeah, depends on the circumstances. time kinda flies when i'm alone and occupied, and i often end up feeling like i didn't get enough time to finish all of those grand ideas i had at the beginning of my isolation period. sometimes i get restless and need to take a walk or a drive though.
hah, singing and dancing is probably my strangest thing. sometimes i speak out loud, practicing spanish, thinking aloud to myself, or otherwise speaking fun or meaningful words (like practicing accents or reading poems). i dunno i probably do other weird stuff too. that's the nice thing about being alone. whatever weirdness comes up, you have the option to entertain it.
