Well, not so much that we leave it often, but more like we left it once in something of a crisis and haven't gone back.
[Keith didn't regret the decision, but he did sometimes wonder if the others felt homesick. He really didn't feel like he had much to go back to Earth for, but he knew Hunk and Lance had families to go back to, and he was sure Pidge would want to go home once she found her father and brother, so it would probably be nice to get back there at some point.
And it would be familiar, which was something he could actually appreciate. Familiar food, familiar surroundings, being able to read the signage, telling time in units he recognized... He was slowly getting used to things as they were now, but he understood missing something he knew.]
