When expressing a desire to be alone, loners may not reject human contact entirely. A common example is that of the person who shuns any social interaction with colleagues beyond what is necessary for fulfilling their work or school responsibilities, mainly for practical reasons such as avoiding the complication of their non-personal life, but who is also highly charismatic during social gatherings with people outside of work or school—or vice versa.[14] Somebody who can be a loner would also fit the criteria for introversion, possibly due to both their innate personality traits as well as their life experiences.[15]
