I do not know if it's intended - but the picture and the story convey the same message in my mind/ in the story - your friend sees your weather as super cold and uncomfortable and his brother, even when experiencing this weather so we would maybe assume he will see it's not so bad - goes the same way. but in your eyes - this weather is pretty great!
now - in your interpretation to the photo you write "Don't know if you like it but it does warm one up during the cold evenings" and " what I love the most about it is all those happy people enjoying their time in cold weather" - this coveys the same thing in my eyes, to you it's a lovely scene and the weather isn't bothering you at all. but you are aware that other people might see it like a cold and miserable situation.
the photo expresses just that - in one picture - you can focus on the cool blue center, or on the warm and welcoming edges.
It's like many situations in life - one place can be heaven to one and hell to another.
