thats weird

Today, I swear to god I thought I heard my parents fighting upstairs. I was downstairs playing around with my macbook and I heard shoutings. Seriously I was like, "are you fucking serious there fighting again?!" I listened for a bit. Then after awhile of hearing the shoutings, I couldn't take it anymore so I went upstairs to go talk to them. While I was half way up, I heard them talk to each other more and they sounded like nothing happened?! They were talking about some random shit now in normal voice. But I could of sworn they were at each others throats while I was downstairs. Idk anymore. Maybe Im just going crazy. Too much fucked up shit in my life.. K Late.
