I remember last time when I stayed in my grandparents' house, the only room which has aircon is my grandpa's room.
So sometimes I will sneak inside the room to enjoy the aircon while he takes a nap in the early evening before dinner time.
Then when dinner is ready, my grandma will come look for me and we will go to the kitchen to have our dinner with everyone
Back then most places have no aircon but seems alright. At night even feels a bit cold sometimes...
But now the weather is unbearably hot from morning to night
