[It takes far more effort than it should to refrain from saying something flirtatious in response which - No, even accidentally flirting with your partner's sister is just Not Cool. It's even worse considering that the sister in question is in a serious relationship. But they avoided that landmine to trip into another one:]
Your sister is really hot!
[It's not said in a 'I want to bang her' kind of way but like 'goddammit she's at least as hot as me, but probably more so'.]
I can't look like crap in front of another hot woman!! It's illegal! She's not going to respect me! Oh my god, does your sister think I'm lazy?!
[She's not wearing any makeup, she's still in her short shorts and a dumb tank top and you can probably kind of see her bra through it and! And! AND!!!!] ..... At least you two hugged, though, it was really sweet.
[But also she's going to look motherfucking flawless at lunch to make up for this unfortunate oversight.
Hope this mood whiplash isn't causing any muscle pain, Krieg!]
