gollark: Language is complicated and comprehending gollariosity in its full glory is difficult.

gollark: Fascinating, but I need to hear it from <@593113791252660224> because <@738361430763372703> could be lying.

gollark: <@593113791252660224> Are you <@738361430763372703>?

gollark: Great, thanks.
