That, I thought was, obvious when he mentioned the ten day waiting period in Kali (California).I take it you’re not from around here, are you?
As for DROSed, I had no clue either.
The thing is, in either instance just mentioned, it is confusing when people write or speak using abbreviations and acronyms expecting everyone to know what they mean. I try to avoid doing it, but guess I am guilty of it sometimes myself. Some acronyms like ASAP are so popular I would think any adult (who is an American English speaking person) knows its meaning but I found out recently not everyone does know it (although now at least one more person does after I explained it).
