I worked at the zoo a couple summers ago. I amicably quit after about 9 months. I'd like to go back to work there this summer. I still have my boss' phone number and email.
Would it be best to text, call, or email? She's older than me, probably in her 60s (maybe 70s?). I would feel really awkward about calling someone out of the blue, but I wonder if that's normal/expected/appreciated to those who are a little older.
I'm probably overthinking this but I'd just like to know what the best route would be here.
