How does a Buddhist care for others' suffering?

Please forgive me, I know really little about buddhism. From what I heard, the Buddhist will try to find relief from suffering by meditation and trying to be selfless. But what about others that are suffering? Does the Buddhist value more attaining enlightenment for himself or helping others in need? Also what if others do not have the skills to practice to go towards enlightenment? Is the Buddhist concerned? I'd like to understand more the relationship between the Buddhist and the suffering of other people.
