I think people forget that phones can still be used for voice conversations. I get so many back and forth text messages or email chains on a day to day basis. In the hours that pass trading notes, the discussion could have passed and resolved in a handful of minutes. Texts make sense for updates. Emails make sense for a bigger pile of information. For making big decisions or catching up? Not even close.
Call someone. It’s quicker, more personal and less ambiguous.
