I thought my friend was gay until I saw her pics

My friend has a few of these pics of her with a guy on her snap but I didnt think anything of it because she is a blonde so most of her snaps are of straight girls. One day I went to her and told her about her snap and I was like "oh man this one looks a lil different" and she just laughed. Then she sent me this video of her getting super excited and stuff and I thought nothing of it. I told my friend about that and she was like "oh man Im not gonna believe you. I have the videos and it looks like its you" and I was like "what the hell. I dont believe this. I sent you the videos. I have them. Youre not even the blonde one. Your friend is black." And I was like "fine, whatever you need. I just thought it was funny." But the next day she was like "wtf? I didnt think anything of it, it was a normal reaction. She just sent me a pic of them on the snap. She was playing with her hair like a weirdo lol
