It is cloudy today, which is hated by almost every people on this planet.
Why say so? Because on one will enjoy doing things on a overcast.
If someone unforturnately come accross such a day whose sky was spread by countless thick grey cloud, he most probably may choose to stay indoors instead of going out.
Psychologically speaking, one morning when you wake up and decide to have a walk outside, you get everything prepared only to find it overcast, which, out of question, weaken your vision and decrease the sunlights. The weather let your mood become bad and extinct your vigor inside gradually.
Physically speaking, many mid-aged and elderly people have got some old illnesses which usually never show up and ache except certain specific day, so they will be subject to a lot of physical pain on a overcast day, for example, backache, legache, headache and so on. As a result, it is a day that caused old people collectively feel painful and indirectly torture their mentality.
