Okay so I have this super cute boss (she's 22 and I'm a guy 21) and I feel like she's flirting with me but I'm not sure. We are always making each other laugh hysterically at work, she playfully hits me every now and then, and she pulled the really cute sad face and wanted me to tie her shoes. So do you guys think she's flirting with me and if so, how do I go about flirting back to my boss?
