I once admitted to trolling on the IRC in RTB3. Got banned from it for two years. Learned my lesson.
A lesson is a structured period of time where learning is intended to occur.[citation needed] It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor. A lesson may be either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time during which learners are taught about a particular subject or taught how to perform a particular activity. Lessons are generally taught in a classroom but may instead take place in a situated learning environment.
I have gained naght of this. Nor shall I.
