Whilst I was working abroad my DH invited an old friend of his and his wife to stay in our house, when he discovered that they were holidaying in this country. During their stay my husband had, himself to go away on a business trip. Our Dc were away also. On his return my DH discovered their adult daughter, who we dont know, was staying in our Dd's bedroom, his adult children who,we do not know were visiting our house regularly, and my Dh's friends were regularly entertaining peoiple we have never met in our house.
They ate our food and drank our wine and since they returned down under we have not heard from them again and twelve months have passed. I feel miffed. AIBU?
