I've been searching both my mind and several thesauruses attempting to find the adjective that best describes this type of person.
The term "thick-skinned" is the closest to what I am trying to convey, but that carries the connotation that he/she is callous and does not care about others.
Is there a word that describes someone who is not easily offended -- able to withstand criticism, ridicule, or jokes made at his/her expense -- without also implying that the person is emotionally callous?
