There is also what you would do on the telecommute day. For instance, when I telecommuted, I could work any hours I wanted to, so I woke up, did some work, had breakfast and put a load of washing on, worked more, hung out the washing, worked, had lunch and went out and got the groceries (maybe these were separate), worked, put on dinner, worked, and then finished work when everyone else arrived home. This assumes that the day you choose is good for doing all the extra tasks - some shops aren't open on certain days, and washing may be better done on certain days.
