A relative of mine is doing me a favor. I didn't ask him for it, he offered it, but I'm genuinely happy that he wants to do it for me. He promised me to do it this week, but today he sent me a message telling me that he didn't have time this week due to some stuff going on in his office.
I'm completely fine with that, it really isn't something urgent and in the end he's doing me a favor, so I'm sure not going to complain if it takes some time. The problem is that I don't know how to word this properly.
My goal: I'd like to communicate to him that it's really fine if it takes some time and that I really appreciate his effort, without pressuring him or anything like that. Ideally someone would make an example how such a message could look like.
