Tell it all or nothing

Yesterday, a pastor came up to camp to pray for us as a camp and for our church that we attend -- it's actually not our church, only 2 families at camp attend it, I never been there, but pastor didn't realize that. 

In the conversation he kept talking about the pastor and the family and all these details that communicated to me that something really bad was going down but didn't know what the bad was-- 

At dinner, there was some people from that church eating dinner at camp (completely unconnected to the pastor that came and prayed for us) and I was telling my boss about the situation that occurred earlier. 

He had lots of questions, I had no answers, so we asked my new manager, who attends a church loosely connected to that one and has friends who attends the church of topic. He knew more than me, but still had only vague answers nothing had details. 

After dinner, I was getting a ride home from my boss, and he turned and said to me. " I hate when people don't tell the whole story, you either need to say it all or nothing at all" 

he constantly only tells me half stories, or make blank statements that tells me there's more to it, but doesn't tell me it.

So I perfectly replied "kinda like when you need to buy a pregnancy test and not tell the person you are with what or who you are buying things for?"

I got a laugh and "Yep, exactly like that" as a response.
