roleplay where my wife pretends she doesnt know me, gone wrong & gone right

k so this is one we've been doing for a couple years and its hands down our favorite scene. premise is simple, im at a bar (usually a hotel bar in birmingham or wherever we are), she walks in like a single woman, doesnt know me, im just some bloke trying his luck. the times its gone right are mental, like ive genuinely felt nervous chatting her up cos shes that good at it... the times its gone wrong? a real bloke chatted her up first once and she had to ditch him politely lol, and another time i got too nervous and forgot what i was doing. anyone else play this? whats ur best disaster story...
