Don’t speak about your strength in front of a someone who’s weak,

Your happiness in front of someone who’s sad,

Your freedom in front of a prisoner,

Or your money in front of someone who’s poor.

Weight your words and consider others feelings.

In mathematics, a Fourier series is a way to represent a wave-like function as a combination of simple sine waves. More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials).
