I have my desktop computer where I do my own stuff like games in the same desk where I put my work laptop, and yeah sometimes it feels like I'm never really done as the transition is just closing the laptop and switch the monitor input, one thing I like though is that we do mob programming so when it's over it's truly over as we share responsibility rather than me having to finish something on my own before a deadline.
But yeah I'm thinking of putting a second desk in another room for work, I don't want my own house to feel like an office.
