Since/if you live in the USA, tell your friend to put the sticker on his/her nose. And walk down the busiest street in his/her city, town, or neighborhood. And when someone; asks, “What is that on your nose?” He/She can reply with, “It’s a new GoPro surgical implant!”
Please understand that this forum is not just for the USA. Are there any words you do not understand in the new (USA only, 1975) law?
