Good to hear from you...
[Two paragraphs of pleasantries about him and his recently improving health omitted]
We have recently made plans to re-design the garden to include a scaled down version of the bamboo forest and to include flowers as part of the first stage of implementation so that the yard can be used and provide a visual focal point.
I will keep your offer in mind if plans should change. I appreciate you interest and offer. But our hope is to be able to utilize and enjoy the yard once again.
[Two more paragraphs of pleasantries omitted, one about where I can find a community garden, and another complimenting me on my garden].
My question is, who is "we"? I think "we" is just him. He lives alone in an otherwise empty two-unit building. Not once in the six years have I've lived next door to him have we seen another person come or go from his home.
Reading between the lines, I suspect an offer of ornamental gardening would have been more persuasive than my offer of vegetable gardening.
