Occasionally I come across a neighbor who just doesn't understand the game mechanics for gifts and material requests. Unfortunately, they become rude and irritable and outright demanding that they won't accept your material request unless you accept theirs first, so I felt it was time to post about this to explain to others who are unaware of how the game works.
If you request materials for a new appliance, there is a limit to how many friends can accept those requests each day. Based on other information in the forum, I believe that limit is 20 items. If 20 neighbors accept your request for an item, all other requests you made for items for that day will disappear from the remaining neighbors' News. I have received alerts that a neighbor requested help only to find when I loaded the game that the request wasn't there. I was too late responding to the request before too many others beat me to it.
Also when you tap accept for a material request, the item automatically is added to the player's inventory. You DO NOT have to send that item as a gift, but doing so can help your neighbor build faster. Gifts and material requests are two different things. I have had neighbors refuse to accept my request because they didn't see a message that I sent a gift, when in reality, I had already hit accept on the material request. Sending a gift is independent and results in a second item. Please keep that in mind. Some people like to use gifts to send food instead of parts. Others have a habit of sending parts that aren't even in demand. When there is no goal to build an appliance, anything is fair game, but while material requests are being made, it's a good bet to gift the same thing that was requested so they get two of that part instead of one. Keep the daily limit in mind, though.
Like material requests, there is also a limit to how many gifts a person can receive in a day, which is also 20. If you try to send a gift to someone who has already received the daily limit, you will get a message telling you so.
Please don't be greedy and refuse to accept material requests from your neighbors because you insist that they respond to your request first. As explained above, you probably have a lot of neighbors and have already maxed out what you are allowed to receive for that day. That is not your neighbor's fault, and it is not for their lack of trying to send you a gift in place of the missing material request. Be thankful that you have enough neighbors to receive the daily max, and be a friendly neighbor and hit the accept button. It's not that hard, and it costs you nothing!
