Continuity mistake: When Michael Myers busts into the bathroom stall occupied by the truck driver, the glass on the framed advertisements on the opposite side of the stall is broken and we hear glass hitting the floor. When Myers leaves the stall, the glass in the frame is still intact.
Answer: Laurie's father, Mason Strode, is a realtor who owns Strode Real Estate, and there's a realty sign post in the front yard of the old Myers house. Mason tells Laurie, "They're coming by to look at it later," so we know he's talking about people interested in buying the old property. When Michael sniffs the envelope we see the Strode Real Estate logo, and it presumably contains realtor's paperwork which is pertinent to the sale of the house, and is meant for the people who will be coming by later.
