stalk someone secretly for fun

I’m going to do this.
But I think instead of randomly picking someone from a crowd, I might find a streetname I like in my city and then stalk the first person I see on it :D unless they drive. Then I’m screwed.

My only previous stalking experience was following an old man walking through the town for ten minutes. And then getting incredibly excited when he stopped to look at crumpets ¬_¬
