"He is a terrible planner, though. So am I"

Linda McCartney's quote is likely describing her and her other half's lack of preparation abilities. She is indicating that both she and her partner are dreadful planners, and that they both have difficulty with preparation and organizing. This could be describing anything from planning a holiday to arranging a household spending plan. It could also be referring to their ability to plan for the future, such as retirement or long-lasting investments. The quote indicates that Linda and her partner are both chaotic and lack the ability to prepare ahead. This might be a source of disappointment for the couple, as it can be challenging to manage life when one is unable to plan ahead. It might also be a source of humor, as Linda has the ability to laugh at her and her partner's lack of planning skills.
