They haven't contacted me yet

I have been followed by a light skinned black man for years
he is about the right age and so am I (well I'm 60 so a lot older than him)
He proffesses to have a serious 'crush on me'
he has recently seen me unloading my car and knows where I live so he came back and knocked on the door and offered his phone numberi declined and told him he could do a lot better (no point in being nasty to people)
He now cycles past and drives past He has a great big manky green van that looks as though gypsies live in it and claims to be a musician

Should I be concernedhe hasn't done anything wrong to me and may obviously be someone totally different
