Get a bicycle is a good idea too, get a second hand one, those ppl put in house never use for long time. My friend paid RM29.99 for a 2nd hand bike, and another RM30 to replace this and that in the repair shop and walla he everyday can cycle nicely to uni....

Very dangerous to walk alone at that time for that long. Of someone is paying attention to your routine, it could be tragic for you if they come out with a plan later on.
