A thorny problem

Have you ever tried smoking a roll-up outside when it's raining buckets? Well I've cracked it and what you do is this: turn the lit end inwards and under your palm, then shield it with the said palm while you take the occasional puff. Sorted! What I haven't worked out, however, is how to keep one's clothes dry while one smokes. Oh well, it's back to the drawing-board.
