If you see someone without a smile, give him one of yours. An idea from Gopi

ups, sorry, saw your video even right now (after posting my idea) - so I'm lucky we do both the same, and i will post another idea ;) Good luck for your project, what a beautiful idea :)

No problem!! I'm actually executing a very similar idea again this month. As a little aside project, smiling is very popular :-)
