Thaha_Payen - LOL. I can only tell you in all honesty that I am not sum_off. I enjoy reading him but he is in a league of his own and my writing, unlike his, is mostly random rubbish. But I'll take your comment as a big compliment :) Vantage Point - As I often do, I'm scratching my head, this time on the "vacum and tunnel effect". Kabi haru ko bhasa bujnai garo! ;) Sum Off - sorry for stepping into your thread with this aside but I couldn't not respond to TP and VP.
