I pride myself on being a generous person ,and no one could accuse you of being mean,but we must all beware of people like him.He is the kind of person who lives on other people and their
generosity,and we all suffer from them.
When you frist met,you said,he was very friendly.Did not you suspect him of anything? He might have been friendly,but he was obviously mvesting in the future!
The thing how is for you to decide on a course of cation. The question is:how to get rid of him and his family-either shortly after they arrive or preferably before?I wouldn`t dream of telling you what to do,but I have one or two suggestion.
