28 degrees (C) is nothing lol. Come to FL and see how you like it.
Plus, anyone who's been to Dubai in the peak of the summer (July) knows what hell feels like lol. it was 48 degrees C during the day and 41 at night. I got used to it after a week or so though, it's like being in a sauna 24/7 (and my skin looked amazing).
How hard is it for some of you to understand that this is England. Everything we have is made for the cold and dreary. We are used to the cold and wet, not the hot.
The majority don't have AC, we have heaters and double glazing windows. Heck, between 10 and 20 is usually the best we get.
