This is a bit weird but I do need some opinions.

I met a new lady from our area a few weeks ago at another neighbours place. She and I got talking about how she wanted to revitalise her gardens and paddocks. I offered to save some horse manure for her so she could come get it in the trailer. I didn 't hear from her again until last week-end when she rang to ask if she could get the manure.

I generally spread it on my own pastures so I didn't have any prepared for her to collect (ie in a big pile). Keep in mind I am doing them a favour by giving away manure. I have a very good pasture improvement program using my manure. They are in no way assisting me by taking away waste. In my conversation initially with this woman I made that fairly clear.

I said I'd prepare some for her to collect and all last week I creted a pile of manure for her to collect week-end just gone.
I didn't hear from her until Sunday arvo. She rang at 3pm and asked if she could come get the manure. No worries.She rang again at 4.30 and said she couldn't make it until 5.30. 6pm rolls around and we are doing "dinner bath bed" routine with DS and she still hasn't arrived. I ring her and get her OH. He says they aren't coming now as he's "busy" watching car racing on TV. He said they "might pop in" during the week and collect the manure.
It's now Wed and I haven't heard from them.
1. Do I keep adding to the pile for them or take the easier option of continuing my normal spreading routine?
2.Do I start (the quite large job) of re-spreading the large pile I created for them?
3. Do I ring them AGAIN and ask what they are planning to do?
4. Do I tell them they can come and collect if they do ring or tell them "sorry thought you weren't wanting it now" and forget the whole thing?
