No one bothers to leave me voicemail ~literally knocks on wood~. If they start leaving me voicemail I'll rage, because boost voicemail is total ***. You have to listen to the entirety of any message to do anything with it (including delete it).. No skipping it, no preemptive deleting.
But yeah I don't answer these calls right now, except the occasional new number that pops up and I go "well that could be friend/family so I better answer it".
