Future+Perfect+Continuous

__USES__

 * We use the Future Perfect Continuous to show that something will continue up until a particular event or time in the future. It is related to the Present Perfect Continuous and the Past Perfect Continuous; however, with the Future Perfect Continuous, the duration stops at or before a reference point in the future.
 * Example: They __will have been discussing__ that for a couple of hours by the time you can call. I __will have been painting__ the house for a week when you arrive.
 * It can be used as well to show cause and effect.
 * Example: Laura __is going to have been sleeping__ for an hour when we get home, so she will not be tired. Mum __will have been cooking__ for four hours by the time we start eating.
