I will choose a sunny day, because I can go to the places I want so easily, enjoy the outdoor travels, do some hiking and relax while staring the beauty of nature. You can also transact business such as selling goods and services on field to your probable client. No hassles, flood and traffic. You can play badminton or tennis. So cool. You have no difficulties on drying up your clothes and most of all is that I am on good mood, so energized. I have no difficulties to plan my activity ahead during a sunny day. It is much easier to drive. You can also enjoy an outdoor party with friends and relatives at your garden. So I guess that's it.
