Hi  kiyomi
can give you over time..free too
If you need any help in learning Modern Standard Arabic (MSA) and classical Arabic, I can help you speak the language. So, if you want to learn, you are welcome to contact me and I can teach you these things easily in a short time.

We use the word waste in various ways to convert some these same ideas. "Such a nice gift would be wasted on me." and such, but not quite the same depth of meaning as the Japanese word.

I can't help but think about things in Japan like waribashi, the massive amount of bottled water purchased due to minor flavor differences in perfectly safe and healthy tap water, the use of tsukaesute oshibiri, multiple layers of packaging you have to go through just to get to the individually wrapped items inside, etc. there is an awful lot of waste that much of society never thinks twice about.

Children around the world die every day due to lack of clean drinking water yet we go to the nearest jihanki and grab a bottle of mineral water because when we drink out of the tap somewhere nantonaku tetsu no aji ga suru. Donating that money could literally save someone's life, but we are so zeitaku here that this stuff is all part of daily life and not frowned upon at all.

I know plenty of people who when they travel put bottled water into the hot water heater for the waste to put in their tea, coffee, or cup noodle because the tap water doesn't taste good enough.

I would love to see a campaign to raise awareness and make change here as well!

:)  Thank you...

I liked this article a lot.  Could you put hiragana for the kanji, though, please and thank you?  Very interesting in-depth explanation of a word I've heard before but didn't realise was so full of other meanings.
