What does an Introvert look like?

Introverts tend to be more comfortable spending time alone, gaining energy from situations with low levels of external stimulation. While they are often capable and successful at socialising, it can drain them of energy and they will likely need time alone to recover and recharge afterwards. Similarly, if an introvert does not have the energy to attend a social event they may choose to avoid it rather than suffer through it. This is not through rudeness but rather an understanding that the event will be demanding and will probably leave them drained.
