Pretoria's 'Hobo with a Smile' chats to Rian

For the past five years, Steve Loock has stood at the intersections in Pretoria's suburbs with a sign that says "hey, smile". 
Loock shared a little bit of story with Rian, explaining that though he may be homeless, he is not a beggar. Instead, he says, he offers a service to commuters by reminding them to take a moment to appreciate life. Loock has been living "in the wilderness", as he describes it, for 19 years. 

Those who have met Loock have snapped a photo of him with his colourful sign to remember the moment.
