What the heck

I'm sitting in my bed while I hear my friend raiding my fridge lol.. I haven't had friends sleep over in years probably since I was in middle school. I'm fucking 19 years old and I feel like I'm too old for this shit. I'm honestly not that close to this girl either and she insisted on spending the night. The nice gal I am agreed because she's going through drama at her house. But dang is this girl different at my spot. Perhaps I'm overreacting but um she's smoking my cannabis willingly (I have a medical card, can't say the same for her) and then complains about being "too high"....... Then do not smoke? Right? Well no she's getting high as a kite and then literally munching and eating the entiiiire time. I shit you not we were at a place for over an hour and she ate the entire fucking time. I just don't get it and maybe I should be more understanding but it seems like she's eating like theres no tomorrow. I don't want to be rude, I'm probably just gonna ride it out until when I gotta bring her home. &I don't technically need or want advice I just needed to rant. I now know to never have a fuckin sleepover with someone I'm not that close with. Lmfao
