Back in 2014 I thought one of my co-workers had worn the same t-shirt 2 days in a row, so I criticized her on it. She corrected me, she was wearing Mossimo (Target brand), and the day before Faded Glory. I was like wait, you shop at Wal-Mart for clothes? I told her, I had just assumed she went to stores like Forever21 and LensCrafters (she got her glasses from a local optician).
We had a boombox with the radio on it and one day there was like 4 Lady Gaga songs in a row and she made a comment they were playing alot of her songs. So from then on whenever Lady Gaga came on I'd ask her who sings it? One day "Raise Your Glass" where the first 30 seconds sounds like Gaga song...I had her fooled, and then when the chorus came and I revealed it was actually Pink who sings it. So from then on we'd have music discussions every day and we were talking about what concerts we had gone to and I mentioned an upcoming drake/future concert I was going to. So we ended up going together and having alot of fun.
After that we'd do little activities together like going to the mall and I unintentionally figured out I could use her as bait to holla at other chicks. One time we were at Bath and Body Works and she was tryna buy me some kind of cool aromatherapy gadget but I didn't think the scents they had available were "manly" enough. There was another chick shopping so she approached her and asked her for an opinion on which scents were gender neutral. So anyways I guess that broke the ice and I ended up having small talk and got the chicks number who was FAR out of my league (she was the type who goes to tanning salons, goes jogging like every morning). All thanks to my (average looking) co-worker .
Be prepared though, having a platonic female friend involves alot of mundane conversations and listening. I had just assumed she was on Direct Deposit and was shocked to see she not only got a paper check she also cashed it at the same gas station in the hood. She told me a story of how her car insurance had caused her bank to overdraft, which should've taken less than 5 minutes to explain, ended up taking a full half hour to explain it and I nearly fell asleep while at work.
