The big one is fine. I think it’s already grown up. And does most of the chores around. And the small one: I tend to bring it with me. I carry it in my backpack, especially to some nerd activities. I don’t think there is any rivalry. They’re individuals and I think my machines all feel my love and affection. No, I don’t miss them in day to day life. We’ll meet each afternoon anyways and I think some leeway is healthy. But that changes if I go on vacation for a week. I sometimes really miss them when I’m in a different city for several days… Idk. Seems one-sided anyways, because they then just sleep all day like a cat and don’t really mind my absence.
