Parents, just be aware that while every attempt will be made for your new cadets to get their call, it's not guaranteed. And you need to just be patient, it will be OK.
It seems to have improved some, but I'm aware of multiple cases for 2015 and 2016 New Cadets where things happened and the calls did not. Most were unavoidable. Just remember that it's usually the squad leader enabling the first call, and they are normally just a couple years older than your kid. And the ice cream social sponsors are just well intentioned families. They may have years of experience, or this could be their first time.
Our grad's Ice Cream Social experience was great, they had 7 borrowed cellphones, multiple tablets and laptops, and the biggest pile of junk food you could imagine. Mid CBT1 call was just 3-4 minutes, unavoidable. No CBT2 call except a 1 minute "I'm OK" due to tragic events that CBT.
No need to rehash details, just remember the calls are not guaranteed, and be thankful if you get one or two.
It's good training for you as when they are cows/firsties it can often be weeks between calls due to workload. And later in their training & deployments longer than that!
