with sincere gratitude
心から感謝して
"I thank you from the bottom of my heart for everything."

a very good and honest person
using creative and low-cost strategies to rapidly grow a bus...
to ignore distractions or unpleasant thoughts
used when someone has responsibility for something
an early warning of potential danger
to keep one's plans or ideas secret
