Our garden backs onto a canal. We have space for one mooring. Our garden is adjacent to a place where lots of boats are moored. We occasionally chat to the guy who parks his boat near ish to our housein this marina. He has asked if a friend of his can park his barge in our mooring spot for a few weeks until there's space in the marina. DH said yes without thinking. I have asked him to rescind this offer as I'm not happy with a random man having access to our garden (even though only a gate stops others entering) My thinking is that I have no clue who he is or his history or how long he will stay. If I'm honest my real concern is for the children and that potentially it is an opportunity for grooming. I do supervise the children in the garden but it's possible one would be playing at that end of the garden if I were with another child in another part of the garden. DH is being very reasonable and has said he has no issue taking back the offer. Just wanted to double check I'm not being over cautious. I like to help out and we do have a free mooring spot but it doesn't sit quite right with me. Thanks.
