Na lotfan bezar goosh konim.
This reminds me of a funny story. My uncle was at his friend's house and Golpa was also there. Late at night the host insists that Golpa sings. He keeps taarofing and then says "na baba deer vaght ast va hamsayeh hatoon bidar mishand". The host said don't worry "inha khodeshoon yek sag darand bazi vaghtha ta sobh vagh vagh mikoned".
