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 talk to my cat. All day long. Or I tell him “I’m here!” when he’s looking for me. What’s weird about that, you ask? He’s deaf. Has been all his life.
