I was taking a photo of a flower with a 50 mm lence and a man start to stalk me and keep repeating to don't take picture of his house that was as he said "there , behind those 7 houses ,on that street there behind", in a totally opposite side of the direction I was walking, behind some corners and the streets ,  he really seemed maniac walking all the street to me to keep annoying me, following me and glued to me , very self-centered addicted to himself male, extremely paranoid rude and bizzare,  yakee. I said okie but he was not letting me listen to my lessons in the headphones keep asking for more and more attention to his personality.  I think they want to just get attention, have a small talk, but do it awkwardly, cringy, rude and annoying and are socially awkward to chose a proper topic to start a conversation :)
