Look mate; you might want to sit at home rather than have to travel, but you took the job of MP knowing the terms and conditions. If you can't or won't hack it, then step down and let someone else do it.
You might think it would be great watch daytime TV and issuing press releases whilst casting your vote electronically, but in the real world you have to do your job to get the fat pension and the fat expenses.
Are you really that disillusioned already? If so, resign and fight an election on the slogan of "Virtually Representing You".
