My friend and my mom are having a fling...i think?

Well i was in the kitchen and my friend jack came along and sat in the kitchen next to me and starting eating cereal when i didn't even tell him to get any. When i asked him why he took it without my permission he just says to me that my mom has given him permission to do anything he likes in my house. Then my mom comes along and she's dressed all y and stuff without ish makeup and she just puts the radio on and starts twirling around and then jack just gets up and very creatively starts drumming on my moms when the drumming part comes. I just sit there and look at them with my jaw dropped and as i've lost my appetite i just get up and go upstairs.
