Before someone goes buying, there’s a reason they go shopping.
There are usually a few events that lead to the desire — or demand — to shop. Something happens that trips the initial thought. There’s a spark. This is often when passive looking begins. You aren’t feeling the internal pressure to buy yet, but you’re starting to get curious. Then a second event happens. It could be soon after the first, or months later, but this one’s more serious. It lights a fire. You need to make progress. Now you’re actively shopping.
