What does it mean when a guy giggles around you?

[Anonymous]

there's this guy at my work who giggles at me sometimes and it'll be over the littlest things like yesterday he made me put money in a guys back pocket and he giggled when I did and today when I was running up to the register, he giggled again, and it makes no sense to me. Does he find me silly or something? Also, when we were having a conversation about dogs he randomly said you're a wiener dog and it confuses me

I think he is flirting with the giggling. And even with the dog joke he was flirting. It could be possible that he likes you.
