I never carry an umbrella myself, and in fact I often go out just because it is raining, even though I have nowhere to go. I just love the rain, everything about it. I won't get too much into it, but I can tie it down directly to my Fi.
The fact that there are less people out when it's raining helps too of course.
I generally, for some reason, enjoy doing things that are considered unusual, distancing myself from the world that way, makes me feel more a part of it on some other level. Like estranged from people and society, but in tune with the world itself. I'll name some more random activities.
Sitting on a park bench alone at night.
Drinking cups of black coffee in the night to purposefully mess up my sleep.
Staying up all night, just thinking, nothing else.
Sitting alone in a pub, drawing or writing something.
Showering in dark.
Walking in the city, imagining I'm someone else, somewhere else. Changing the way I think and what I think about in accordance.
Leaving little drawings or pieces of writing around the city.
Most of it is Fi, perhaps some Ne mixed in here and there.
