I mean your nice and all
When someone says you’re okay, but they’re just trying to save face and not make things awkward.
You: 'You’re so cool!' Them: 'I mean your nice and all... but I think I like someone else.'
You: 'We’re totally gonna be best friends!' Them: 'I mean your nice and all... but I’m not going to your sleepover.'
You: 'You’re my favorite!' Them: 'I mean your nice and all... but I’m going to the mall with my best friend.'
