Hi, you're back, Sheryl Tollinson, question four, how do you respond when you don't know the answer to a question? Like any other person, let's say, if you worked in a retail store, and you go in that store often, and you're looking for a particular product, and you go up to first you're searching in store for that item in your size, and the sales clerk, or the retail person on the floor, you ask them a question about your size, and it's not in stock right now, and when is the next time that it will be in stock, and if you could fill out a form, a recheck, or whatever, or call back, you would do so, and then, or you would ask them what is the next similar item to the item that you came in the store for, so you wait for the answer, and then once you get that answer, and you fill out, or you have to fill out that form, you wait for the phone call, and then you return to make a purchase of that product.
