Just met this guy

No one ever reads my post but please I'm so confused 😂 so I met this guy and works in the other side of the building to me but for some reason he came into the same kitchen that I was in and started talking to me and I was ignoring him because I got really nervous and didn't want to talk to him but he walked over and looked at me so I had to answer but I completely froze like full on no words (can I just add that I the most confident girl, I do not care about a thing or what people think of me, I once walked around as a unicorn with a cardboard cut out rainbow, besides the point)

But I froze and it's so unlike me I have never done that and I also feel like I've known him my whole life it's sooo weird and I'm so confused like we had one conversation about If I needed a fork (I was making tea but he thought I was making food) for crying out loud I'm so confused would anybody care to explain this please?😂
