2. Talking to Themselves: Engaging in conversations with oneself or muttering thoughts aloud, even in public, is a quirky behavior displayed by some individuals.
3. Counting Steps or Objects: Counting steps while walking, counting the number of times they chew each bite of food, or even counting tiles on the floor can be considered quirky.
4. Wearing Mismatched Socks or Clothing: Deliberately choosing to wear socks or clothing that don’t match in color or pattern can be a quirky fashion choice.
5. Extreme Attention to Detail: Some people have a knack for noticing small details that others might overlook, such as spotting typos on restaurant menus or identifying obscure references in movies.

8. Obsession with a Particular Topic: Developing a deep and detailed knowledge of a very niche or obscure subject, like the history of paperclips or the taxonomy of fungi, is a quirky intellectual pursuit.
9. Alternative Transportation: Opting for unconventional modes of transportation, like commuting on a unicycle or a pogo stick, can be quite quirky.
10. Overuse of Certain Phrases or Words: Repeatedly using specific words or phrases in conversation, or inserting unusual vocabulary into everyday speech, can be a quirky linguistic trait.
11. Collecting Stamps or Coins: While stamp and coin collecting is a common hobby, some people take it to an extreme by collecting extremely rare or obscure items.
12. Personal Superstitions: Developing unique superstitions or rituals, such as avoiding cracks in the sidewalk or wearing a particular item of clothing for good luck, can be considered quirky.
13. Extreme Minimalism or Hoarding: Going to extremes in either decluttering possessions to the bare minimum or accumulating a vast number of items are both examples of quirky behavior.
