I'm a man who's happy to talk about any topic if given context.
When given a task, I always grind away at it until it is finished efficiently and effectively.
If I'm alone, I'm often going through the list of tasks to do and will often leave a note of where I'm at if anyone wants it.
I'm very relaxed to whoever I'm with (as long as they don't impede my space or steal my stuff) and will listen and help with any problems a person may have if they ask for it.
