You’re looking for a new flat with your friends and today you saw pretty good catch on the internet. You called the number and asked for an appointment to check out the house. You loved what you saw from the outside. The house looked lovely and it was in a good neighbourhood. The street looks like if it was in anywhere in Western Europe. You couldn’t wait to go inside. The estate agent walked you in, but suddenly she got a phone call. When she returned, she asked for your patience and left for 10 minutes. At least you could check out the house thoroughly. When more than 20 minutes passed and she was still nowhere to see, you wanted to leave. However, it seems she locked the door when she left. Let’s not wait here, leave!
