"Fool", you observe. Much better word than "Twat". Take heed, & learn, my good fellow. I flatter myself that, here from the security of my own home [not "a Home", note], I can bite just as hard as you if need arises, tho fewer of my original teeth survive probably. I could match your pathetically abusive efforts in rational exchange any day of the week, & you better believe it, Sonny Jim!. So watch out for your own metaphorical 'jugular', you silly little chap.You are, after all, not such a bad old thing at that -- as I might have observed previously, but poor pathetic old survivals like me must be indulged to the extent of the occasional otiose repetition, or what a sad old world this would be for lively young things like S. Shaw Esq to come to eventual maturity in, to be sure.
