next time

This is an excerpt of a news I read in Hindustan Times:

>>>
New Delhi, January 23, 2010: A 32-year-old man was beaten to death by two young men after he protested against their urinating on his wall in west Delhi, police said. According Delhi Police data, the Capital saw some bizarre murder cases in 2009 as far as motives are concerned. Among these, figure cases like a man murdering his neighbour because the latter had kicked his dog at Ranhola village in Outer Delhi. In another case, a man was killed for breaking the queue at a public toilet in Civil Lines. In New Friends Colony in South Delhi, a man was killed for refusing to let another person make a call from his cell phone.

Considering the above, I would say that next time be careful if you decide to stop someone from urinating on your property, to kick your neighbor's dog, to break the queue at a public toilet, or to refuse to let a stranger make a call from your cell phone. But above all, next time, if somebody stops you from urinating on their property, your neighbor or anyone kicks your dog, someone breaks the queue at a public toilet, or a stranger refuses to let you make a call from their cell phone, then you definitely know what you have to do.
