I'm childless tech worker and I hate working from home. I live in very small flat and I simply don't have space to separate work/home related stuff. I'm really struggling to focus on work task and when I finally do it I have problem to stop working (and end it too late). When in office someone will always ask why I'm still working or I will get hungry and food is waiting at home so I need to leave. Also video conferencing is poor replacement for talking with others.
