Services for you AKA happy birthday :)

Dear dad! This is one of your many coupons from us, Sisters services! This coupon contains three services you can ask us to do for you. For instant: You notice the long grass in the garden and sights sadly to yourself. You really dont want to cut the grass - its so much work! Then, you show us this coupon and realize that you can almost demand us to do it for you! You happily lay down on the sunchair and open a bottle of coca cola zero, knowing that YOU dont have to cut the grass! What a great invention, you think.
