My mum is selling her house. On Monday the estate agent asked if he could come to see her the following day (Tuesday) to drop off some documents for her to sign. She said that she would be out and asked him to come on Wednesday.
She was out for the whole day and came home to a series of quite panicked voicemails on her home phone from the agent - apparently he had gone to the house and when she didn't answer the door had proceeded to spend quite a while knocking on all the doors and peering through the windows, expecting her to be inside. He called his office and got them to try ringing on the home phone, which they did repeatedly. He then even called her solicitor to find out if they had any emergency contacts- but perhaps fortunately the solicitor didn't get the message until the following morning when she was at home to answer the phone.
She did point out to him the next day that not only had she said she would be out all day but that the garage doors were wide open and her car obviously absent.
I don't know whether to be pleased that he was obviously concerned for her welfare or to think that he was a complete muppet for panicking rather than rationally concluding that she must just be out.
