I think its normal to make a comment about the weather. If its bitterly cold, oppressively hot and humid, or even if its a gorgeous day
someone saying something about it doesnt bother me. Sometimes its a way to start a conversation. No biggie.
Just the other day a friend called and asked how I was doing. I replied Trying to stay cool. I see nothing wrong with that and I dont see myself s a seasonal moaner.
I dont care to hear weather complaints on a daily basis, but if someone is prone to doing that I just say Yeah, its summer for sure! and move on.
