So this just happen at the store. Gosh people can be so stuck up for no reason(rant)

So let me start by saying I DON'T have any friends. not by choice just the fact that im a 100% sahm with no life. Lol...Anyways just 1 hour ago I went to charlette russe to buy sandals. I came across a girl I "knew" since Jr high and graduate with her in high school. Well I guess she works there since she was at the register. I haven't seen her in years and we weren't considered friends but we did talk at times during high school....Well for me at least, its nice to see old familiar faces... Anyways I know she saw me lol because she kept walking past me but we were both busy so whatever you know? Soooo I was ready to pay for my sandals, and she was the only one at the register. Soooo me being sweet that I am, was thinking Im going to give her a friendly smile while she's checking me out....Well....that didn't happen. Went up to her and right away she's like"Can you go to the other register?"....So I did ( thinking maybe that one was closed) But then I hear her saying to her coworker ( who was working on the other side of the store!) to come check me out...I was Ummm ok....So as her coworker is checking me out, I see right away her checking out another costomer....I mean whatever you know?✌ But wow like I never did anything to this girl . Even my mom who was with me noticed. Anyways just thought I'd rant little. And I mean its so hard to find good friends now days let alone good people😒
