When you say you need to go see the doctor and get out the inventory to figure out which one..... and then avoid calling them for days.
I even do that half the time when deciding to send a text! But yes in general I tend to prefer any kind of writing over calls or face-to-face. Gives me time to think of a response without anyone watching me or asking me questions on the spot, lol. I've found people don't like much me returning their call with a text.
