Then they have to have these horrid flourescent lights shining at full blast in the middle of the night so that heaven forbid someone is unable to read the .....book....humbug...if someone needs light that strong let them bring a flashlight, or pass a flashlight around but turn off the damn lights at least and have kinder light that is more conducive to singing....candles, lamps, solar candles, firelight...whatever...mg
