One Mystery Of The Universe Answered

Have you ever wondered why there are empty cartons left in the refrigerator, pantry, under the bathroom sink or really anywhere you might find a teenager using anything that comes in a container? I finally have the answer and it was provided by my 13 year old daughter. The scenario: Bugs like to take this time of year to come into the house since evidently they wish to be warm like me inside my house. My mom, lovely person that she is, sprayed my bathroom so there would be no nasty spiders or whatever there to surprise me when my eyes are only half open at 4:30 in the morning when I get up. Thank you, Mom! The bottle of spray was left in the bathroom in the corner and I thought she just was interrupted and hadn't gotten back to finishing. The bottle stayed there for, oh, a week and a half or so. This morning we were talking about bugs and Mom said we needed more bug spray. That just begged the question: Why is there an empty container marked bug spray on my bathroom floor. The answer was promptly given by my daughter who was eating breakfast at the time. The answer is: Promotional Purposes. After all these years of wondering, now I know. The teenage son leaves the empty milk jug in the refrigerator for: Promotional Purposes. The empty toothpaste tube and shampoo bottles: Promotional Purposes. All the empty hot chocolate containers, cereal boxes and coffee tins: Promotional Purposes. My only question now is: Am I being paid for any of this?
