Ah yes, Xmas, tshirt weather, bbq's and you wonder if you need the ac or if you should by sunscreen. This is perfectly normal.
@catraxx This is so. I live in the northern hemisphere now, but lived in SA for 10 times longer. For me, Christmas day is spent by the pool playing with new floaties and eating leftovers. You have to braai on Boxing Day.
It feels super weird to me to have Christmas sweaters instead of T-shirts.
