I’ve been talking to this girl at work and she is a extremely sweet and kind person so I wondering if that plays a part into it but whenever I tell how to do something or what to do at work she always responds with yes sir and smiles or when we are texting for another example I said I’ll send you a video of my dog when I get home and here response was ok sir😊 we are both pretty young I’m 20 and she’s 18 I can’t see it being age related I’m not really complaining because I find it super cute of her but I wondering where she’s coming from with it nobody’s else’s calls me sir
