I will be in CA alone, literally, without any furniture for at least half month. Even though the school generously covers all the moving expense, I screwed things up because of my laziness.
Several lessons are learned from this trouble. First, never assume the world is same as you expected, especially when it comes to issues related to others. I thought I had an oral agreement with the rental office that if I move out this month and they find people to take my lease, my last month rent can be waived. However, a week ago, the rental office told me that I have to move out this month and I had to pay the last month rent, regardless the agreement, because the contract said so. But why did not they object the agreement two months ago? This is largely my fault. I should have read the contract and asked all the consequences, especially the adversary ones, when I submitted the moving out notice. It was them who tricked me into this trouble, but it was me who is stupid and lazy enough to be trapped.
Second, everything takes time. It may be ok to assume away leadtime, but in the real world, leadtime plays a critical role in determining the sequence of events. In fact, the difficulty of scheduling and planning of many business is largely due to the uncertain leadtime. For example, I should have noticed the school and planned my moving much earlier, instead of two weeks ahead. Consequently, I should have gave more flexibility in terms of my moving out time. I could have stayed until the end of July. But why did I offer to move out this month (except the rent incentive)? Had not been the prompt response from the moving company (not the school), I would end up in a much bigger trouble. I even forget a very basic principle as an engineering background: redundancy is always desirable, and critical to the reliability of a system.
Besides the nightmare with my rental office, there are still more trouble to experience: I got to pay three weeks car rental fees and live without furniture for at least half month. If our experiences mean something for our future, just wish I do not have to learn in such hard way every time.
