Daily Problem

In our daily life, we always find ourselves stuck with the jolting sounds of repetitive "eh, eh, eh, eh, ehÐ'...Ð'..." and find ourselves stumbling around trying to shut it off.

If one' alarm clock rings loudly at a specific time in the morning, undoubtedly, others will be disturbed. Under such
