is this apology to guests of my Jackie Brown 4K screening sincere enough?

Dear friends who attended my Jackie Brown screening last week. I need to profusely apologize for my inconsiderate, irresponsible and rude behavior. After the screening I discovered the amplifier for my rear speakers was not powered on, leading to a total loss of surround channel information during the film.

I didn't intend to provide a substandard experience, completely inconsistent with the filmmaker's intent, and have decided to seek professional help for my cavalier behavior.

I would completely understand if you choose to not attend any of my further screenings, after this embarrassing breech of trust and complete failure to deliver what should have been an enjoyable evening.
