I’d love to hear about your quirky habits.
One of mine is that when I’m out in nature I tend to collect cool looking rocks, sticks, cones etc. My window sills have become a geology exhibit (and I have zero clue about what I’m collecting, I just go by “ooh shiny”) and more often than not I’ll have small rocks in my pockets, bags, backpacks etc etc
I have a small shoulder bag but feel the same. In UK weather having a thin rolled up coat is indispensible, a water bottle, wet wipes, headphones, mobile battery, lozenges, basic medication, bottle opener etc. Comes in handy. Men have pockets sure but there’s only so much you can stuff in there.
The only problem is when it gets cold enough that I might need a pullover but might not. A bigger bag might be useful.
