You won't have any idea how many neighbours your neighbour has. They could have 20 or 500 for all you know. Therefore it's completely unrealistic to expect them to remember what sort of gift you like on a day to day basis when they also have other neighbours to worry about. I don't gift, with the very exception of if a neighbour writes on my wall asking for something specific, then I will respond and gift that ONE neighbour. I also don't mind gifting back a goal part if it's on the first page of the gifts list, but when I need to scroll several pages to find a particular part, then no, sorry that's way too much effort and I have a life to live. It may sound like I'm lazy and I admit to a point I am, which is why I never expect gifts at all but do accept all gifts I am given out of gratitude. I do accept all parts requests and try to do so in a timely fashion but sometimes, life does get in the way.
