I'm just the opposite. Thanks to a near-miss health issue some years ago, I now carry my own personal summers with me all the time. I rarely need a coat, and stay in short sleeves all year, but unless it's bright and sunny out, I HATE the cold! Dismal skies depress me to the point of suffocation ... so bring on the blue skies and beaches!First day of AC here also, hit 89F. I can tolerate quite a bit of cold but heat- forget it!! I recall as a young child I hated the heat and had mostly cold liquids and avoided heavy meals.
That said, I do upset my kids regularly by leaving the AC off. I like to leave my windows open, which I can't do with the AC running (at least, not until the kids are footing the entire electric bill!) It's got to be pretty oppressive for me to close my windows, especially at night. I think, a least for me, it's more a function of the humidity than the actual temperature. As soon as the air feels like someone just hit me in the face with a wet washcloth, it's time to close up the house and crank up the AC!
