I hate when people act like children

Okay im at lunch right now and I sit with some of my friends, and then there's this girl I don't really know but she sits at the table I sit at 2 and is friends with 2 of my friends here, so she basically every single day without fail asks my one friend if she wants to go walking around, and whenever my friend tells her no she starts whining and saying stuff like "whyyyy" "come onnn" and it pisses me way off like holy shit can u just accept she doesn't wanna go walking, seriously I hate when people act like this when they don't get they're way please stop being so childish you are in high school.

Okay that's all I have 2 say :D
