at this stage of my life, i was not too sure what i wanted to do. it makes it easy to shake on to clean the sink, dishes or anything else. certainly a fire extinguisher and/or fire-proof blanket are wise items to have on hand anywhere candles and incense are burned regularly. as an extreme example, imagine a line with trains every 6 minutes during the first half of each hour, then no trains during the second half of each hour. rinse the mixture out with cold water almost immediately. i actually believe that there are no mistakes, only opportunities.
