You Australian bro?

Don't overthink it. This is just the rapport building phase. If you want a riskier option "Nothing special. Hosting my cult's blood orgy/bingo tournament. So ya know... normal weekend shit" Then I follow her response with "yep, it gets verrry competitive. But then the bingo is a fun way to wind down". This will blow some sets out though. I use it as a means to screen. If you want to play it safer, just showcase that you have an exciting life, name activities that would get her excited to meet you
