Last night, I dropped by the convenience store and bought some goodies for me and cigarettes for my dad. He shouldn't be smoking but he's hard headed. And I gave up from reprimanding and reminding him of the risks. Anyways, I was imagining back then taht perhaps it would be a great idea to invent a nicotine-free electronic cigarettes. So it won't be harmful to our health and will only needs to recharge it to save on buying stick of cigarettes. Hehe. What an absurd idea!
