ha ha ha. 'nice guys' is simply a humor (with a bit of truth unfortunately). Probably, a panel of smart girls researched on their nice guys and drafted their conclusion by addressing the weaknesses of each individuals. Bhanna nahune, afno pani ek duita testai kamjori bhanne ki characteristic chha kya. Dukhha paine ho ki ;). Anyways, lets not become serious on pure jokes and bitch some nice girl. One can read the same joke everywhere in the net. Like in this one: - http://www.thehumorarchives.com/humor/0001030.html
