I can do literally anything that I want to. I know that, whatever time my ride is coming (that is, my siblings), it's some time tomorrow. And the other half of my family certainly isn't coming back so soon. So, that means I can get up when I want, eat what and when I want, basically, do whatever I want to do.
Not even "...within reason", so much as "within physical possibility". Of course, that doesn't mean I actually would. I'm not the type of person to, say, invite friends over for a surprise party at my house, secret, to not be heard of at all. For many, many reasons. But that gives you the kind of idea for what I could do.
...Disadvantage to being alone?
There's only so many ways I can dodge an attention-depraved kitty who was left behind, and now has no fellow cat to pester, no dog to terrify, no human lady to annoy, and no feet other than my own to rub. So while I've gotten rather good at speedy, stealthy moves around the house as to minimize interaction, he still traps me from time to time. I've also got some skill in creating distractions: putting food in his bowl, even though he has food elsewhere. Laying out boxes for him to rest in, even though he rests everywhere. That sort of thing.
It's still something that I do have to tolerate when I move away from the computer though!
