Always prepare you all eat. Yes it is very nice, but would have cost at least twice as much, respectively, to make nice to your parents. Now no one is home, no pope, no mother, no grandmother! Just a great opportunity to have an unexpected surprise of the day and cook something delicious! Do not know what to cook? It's okay! We'll show you. We have a great soup recipe with bacon. Be sure your parents will love. Just do not pull on time, start right now, it is a long process and not simple, they need to have time to come. Proceed.
