A person tries to plan things out to cause the least amount of headache. Sadly that never really works out despite all the planning. Mainly too many outside factors those of course being other people and their plans. For just an example, taking your car in to get new tires. It should go off with out a hitch until you discover that two hour buffer you banked on is no longer an option. Thankfully someone steps in to cover a little bit, then when everything seems to be coming together the bus takes forever to get there and so forth. Thankfully everything works out in the end despite a sent text not being received.
