I recently had a visit from a woman who was a relative of a friend of my sisters. She was visiting the city and had been given my name and my telephone number. Of course, out of courtesy I agreed especially as this was her first visit to this country. She arrived accompanied by her two children aged 6 and 9 whom she had failed to mention. Not a problem as they were well behaved. However, they had brought nothing to keep themselves amused and the board games and baby toys I had were of no interest to them. AIBU to have expected that (a) their mother would have mentioned she would be bringing them or (b) She would have told them to bring something with them to keep themselves amused.
