Harry would have loved the nickname 'boyo' at one point in time. Now, he didn't care so much for nicknames, but he did let family call him nicknames. Ginny occasionally called Harry "Wonderboy", in a teasing and playful manner, and of course Mrs. Weasley (now Mum, since she asked after he married Ginny) called him delightful pet names that seemed to bother her other adult children.
Did he lark off to Tahiti... Harry wished that was what happened. Harry gave Sirius a sad smile, "Or something." He said sadly.
