mine varies cos i work flexible hours but i'd say an average day would be 8.45 till about 6.00
having said that today i left the house at 9.40 and was home again at 5.30, so now i probs won't be home till 6.30 for the rest of the week cos i got a bit of time to make up, but at least i have the option of putting in a short day if i'm a bit hung over or sommat, like today lol
