Parked car in only available space on that section of road near her flat, (not ideal as was within view of flat but no alternative available) 2 minutes before appointment time and called her, and was asked to wait 'few minutes'.
Seen bloke leaving flats as my phone began ringing.
After session I walked back to my car and as I was driving away I seen another bloke entering the flats.
I wasn't hanging around or stalking.
