Block/Charge out of primary

[just another ref]

Somebody here (that person will probably identify himself) said something like:
It's okay to reach out of your primary to point out an elephant on the court, but be sure it's an elephant.

Along these lines, I have said, if you reach across the court to call one right in front of your partner, even if you're right, it kinda makes the crew look bad. If you make this call and you're wrong, it is unforgivable.

IOW, better to say, "What elephant?" than to say, "Look, an elephant!" but it turns out to be a hippopotamus.
