> The teacher is the client. This is absurd. The students are the client. They asked the teacher for ideas for a hobby project. The teacher provided one, then followed up with a question about an estimate. Naturally, a student gave an estimate of how much time it would take to produce the product that they themselves were envisioning. It’s not unreasonable for the teacher to point out additional features they might want to do, and how that affects such an estimate, but it IS unreasonable to call the original estimate “wrong.” It’s not wrong for a particular scope.
