Dear Mrs Richardson,
You don't know me but I am saddened to hear of Mark's passing. Mark lived round the corner from me in Blackburn, what a lovely young man he was. Mark never passed my garden without saying hi to me or my granddaughters, he was always very polite and was never too busy to pass the time of day. 2 years ago on Halloween night he brought his little boy round, thinking it was one of my family I opened the door with a Halloween mask on and I don't know who got the biggest fright your grandson, Mark or myself. I was mortified. It still makes me giggle.
