Order a taxi to take you straight to your home. For this case, I keep telephone numbers of trusted taxis in my pocket. While waiting, eat a sandwich in the nearest cafe :)
Another variant:
- I always wear a rain jacket with a hood outside (if I feel that there will be or is a rainy weather), like this
If you have such a jacket, then pull its hood on your head and zip your zipper. 2. If you know a good way to your home with many bus stops, use it. 3. If there is no such a way or you don't know it, try to get to the nearest underground station 4. No underground or underground stations nearby, then use a way through alley with trees or run through some forest or copse. 5. If possible don't run against the rain so as not allow the rain to pour your eyes, choose the ways to run along with it
And, by the way, if you are planning to use newspaper (non-glossy one), I wouldn't recommend to do it in the heavy rain due to the terrible personal experience. I am not saying this about magazines - they are quite good "tool" to "harbor" from rain.
