Scary encounter

I went to drop my son in his daycare this afternoon and then I thought let me go to the shop and get something, it was very hot and sunny so decided to go home instead, I saw the bus a bus stop and I sat on the bench and this guy around 20 years old followed me all the way from the shops to my house!!! he saw me sitting then sat next to me, He was literally staring at me in the bus I know because he was at the front and I was at the back and there was no one else sitting, he had this weird horny look in his face ,I waited till the last stop to get out, thankfully he got out before me, I just kept staring at my phone pretending I don't see anything 😂
