First, I'd like to address your misguided notion that it would be possible for the moon to "disappear somewhere in the stratosphere". As you can see in the diagram below, the stratosphere is part of the lower atmosphere, beginning about 11 miles above the surface of the Earth and averaging around 20 miles thick.

The distance from the moon's surface to the surface of the Earth is ordinarily about 233,000 miles. Here is a to-scale representation of that distance:

The moon itself has a radius of 1,074 miles, meaning it is about 2,148 miles thick. This entails that the stratosphere would be unable to contain the moon. Incidentally, the entirety of the upper and lower atmospheres would also be insufficient to contain the moon. This is all rather irrelevant, however, because if the moon were to approach Earth in the manner you suggest, it would begin to break apart due to tidal forces when it reached the Roche Limit. Based on this equation:

and the best data available (wikipedia), the Earth-moon Roche limit is roughly 9,500 miles. This entails that when the moon approaches to within 9,500 miles of Earth, it will be shorn apart by the unequal distribution of gravitational force across its surface.
The resulting debris would form a ring around our planet, much like the rings around Saturn. In the unlikely event that any large fragments survive and surpass the Roche limit and continue on toward Earth, they would appear as a giant fireballs upon entering the atmosphere, and upon impact cause damage sufficient to make life here rather uncomfortable (if not entirely impossible).

In the event that moon chunks do not collide with Earth in a cataclysmic fashion, we're still screwed. This is because the moon regulates tides, regulates the distribution of seawater, and stabilizes the rotational axis of the Earth. Without the moon's gravitational forces, the degree of the earth's tilt would fluctuate, leading to the sort of drastic, calamitous climate change that would exceed even Al Gore's wettest, wildest dreams.

Thus, if the moon were truly entering the stratosphere, you (and for that matter, all life on this planet) would have much bigger problems than worrying about whether mommy and daddy "realize this is [your] life" and approve or disapprove of your lifestyle choices. Unless, of course, you think that "sometimes goodbye is a second chance" applies to the preponderance of species diversity on Earth.
I was going to address your Halley's comet reference as well, but I think I've given you enough to grapple with for now.
