I was reading the thread yesterday about entitled random comment men with some amusement as it never happens to me. I spent a few years living in some rough parts of London and thought maybe I developed a kind of hardened exterior that wasn't approachable to these types of men 
Well, that went out the window today. I went to the supermarket, queued at the kiosk and saw a man walk in. We made eye contact and I smiled as is common to do around here. Then when I went to look at the salad all of a sudden he appeared next to me.
He started saying that his dog had seen me and had been desperate for some fuss from me
I was confused and said where? I didn't see a dog? He said 'oh, I was parked up by the hairdressers'. I live a couple of doors down from the hairdressers and the supermarket is at the end of that long straight road, about 5 mins walk.
He starts chatting at me telling me where he lives (round the corner) and various things and I'm just confused. I work nights and haven't been to bed yet so wasn't really with it.
Then he says, 'Right, take this,' and hands me a folded piece of paper. Like a moron I take it. Turns out it's his phone number. Then he starts talking about meeting up as we're neighbours and says I'm a beautiful looking girl I had a mask on ffs, says 'I'll let you get on with your shopping' and leaves without buying anything 
The whole time I just stood there mute. I just feel like an idiot. And when I left with my shopping I actually hesitated going home in case he was still around or followed behind or something. I decided to walk back but keep my wits about me and if he was around then to just keep walking past my flat so he didn't know where I lived. Luckily there were no cars near my place and I checked around before going in.
I feel irrationally spooked and upset. He must have been pushing 50, I'm early 30s. I need to sleep and I have a lot to sort out today too but I can't settle or concentrate thinking I'll bump into him again at some point. He lives really near my local and I have plans to go there in a few days and he's put me off.
AIBU to think he followed me? Talk some sense into me please!
