What if I want to tell a particular friend?
gpt
Yer don't tell him. Dat's all. I had ter pay t'ree hunderd dollars ter learn dis, an' sign a 'greement dat I wouldn't give it erway. Jem Mace tort me dis trick w'en I sparred wid him in Liverpool. He says ter me, says he: 'Buster, ye're a boid, dat's wot ye are. If you knowed der trick of breakin' a bloke's wrist dere ain't no duffer in der woild dat can do yer. I'll show yer der crack fer sixty pound.' He wouldn't come down a little bit, an' I paid him wot he asked. Since dat time I've knocked roun' all over der woild, an' it's saved me life fife times. Dat was a cheap trick wot I got from old Jem, dat were. A dago pulled a knife on me oncet fer ter cut me wide open, but I broke der dago's wrist quicker dan yer can spit.
