On the link between great thinking and obsessive walking
I love walking and there are many parks next to where I live. However I am never able to fully enjoy it or indulge in any longer thinking activities as most of the time I'll be interrupted by either elderly people asking me "to go back where I came from" or random ID checks by undercover police. This happened a lot (5x times) over the last year when I decide to go and walk in a park, once even during an online call with my team. I live in a medium sized city in Germany and come from North Africa / France and it might show a bit too much.
As a mitigation I once seriously considered changing how I look by for example dressing more like a dad or walking the neighbors dog as an alibi for being "normal". Maybe it would have interested the old ladies too, who knows. 
For the time being I'll keep at walking on streets or inside the city as it's less strange to see foreigners there. Can't wait to have my private forest :')
