My brother is proficient in Esperanto and has been part of key Esperanto events in the world.

Never got to peoperly learning myself, but if you want someone to talk about and in Esperanto, organizations are out there, with TEJO (Tutmonda Esperantista Junulara Organizo) for youth and UEO (Universala Esperanto-Asocio) for everyone, as well as numerous smaller ones.
