A time when my family and I were in Singapore,  we decided to visit the Bay South Garden and Flower Dome with Cloud Forest.
I had ordered the tickets online and we went.
It was convenient for us to go to the Garden by subway, because the Blue subway line was just five minutes walk from our hotel.
We got off the metro station, walk a little bit until we got to the  Gardens.
After a wonderful promenade in the Gardens we went to the greenhouses.
I had e-tickets so I prepared my phone.
Фt the ticket control a girl asked me to put the barcode of the ticket on the scanner, but it didn’t work.
She asked me to did it one more time, then again and again.
There were a lot of people behind us and I began to worry about.
The girl said “Increase the brightness on your phone, please”, but I couldn’t remember what the word “brightness” means.
I wrote that word in Google translate and got an answer.
After I had increased the brightness on the phone, the barcode of the ticket was scanned and we passed through.
So I have memorized the world “brightness” for all my life.

P.S. while I was writing the story I thought that It was a rather expensive way to improve my vocabulary :)
