Signs a man genuinely likes you?

We were alone in the parking lot and talking. All of a sudden he sat on one keen and tied my shoe lace (without saying anything).. honestly, I didn’t even notice if my shoelaces were undone. And after that we both went quiet. I couldn’t look at him after that. This is the sweetest thing a man has ever done for me (only my father has tied my shoelaces lol). He is around 12 years older than me. Can this be a gesture that he likes me? We have quite a lot going on (stealing glances, smiles, talks, hot n cold vibes) but every time something happens I try to convince myself that am overthinking. Looking for answers. Thank you.
