Neighbours are flying to New Zealand in a few days and have asked me will I keep on eye on the house, check it once a week as such. They have given me a key. I don't normally mind, however normally when they go away they have a return date. Right now...they don't know when they will be back. It will be at least 4 weeks-6 weeks. I feel like I would like a date as such as I just gave a lot on and I like to work towards a date. We have no other neighbours close by so I am really their only option. Maybe I'm overthinking this??
