I sent someone an email asking a few questions because I only had a few minutes in between stuff.
A short bit later, they call me. I don’t answer because, as mentioned above, I sent the email because I didn’t have time for a phone call in the first place.
Their voicemail said, “I got your email. Call me back when you get this message.”
Look, if I had the time and inclination to TALK to you on the phone in the first place, I’d have CALLED you instead of sending an email.
Just reply to the email, dammit.
