I didn't know until today that the logo of Goodwill shapes G! One of the Goodwill near to my place has an upward arrow on the wall. I thought it is just an arrow which represent 'good will'.
Nyankichi sensei : If you see the arrow from different side, you will see the shape of G!
Frog : that is very common way to use alphabet. In this case, G is smart though.
Yuki: For me it will be Y!
