<human>: This F-up actually happened a few hours ago.

My parents and I were bored, and seeing as it was a beautiful Saturday, we all decided it'd be fun to go to the Shrine of Christ's Passion and walk around the garden. For anyone who isn't aware, the "Shrine" is a series of statues that depict the life of Christ. I wasn't too interested, so I listened to music the entire car ride. My parents, however, are both strong Christians, whereas I'm more lenient in my "rules".

So we arrive and are walking around the gift shop. This is where the F-up happens. I had jokingly said earlier that I was going to buy a Mother Mary statue and some rosary beads, just for fun. Mom laughed, dad laughed, I laughed. Ha ha! 

So we walk around a little, and I get to a back wall with pictures on some racks. Little, small, post card pictures. I didn't know they were postcards, so, without thinking, and somewhat jokingly, I turn to my dad whilst holding one of Jesus being crucified by a Roman soldier and say, "Wish you were here!" 

My dad froze and just glared at me. It took a minute, but I finally processed what I had just said. I had just made one of the most blasphemous statements I could make about Jesus, in one of the most Christian places there is. I explained to my dad that it was a stupid comment and I didn't mean to be blasphemous, and that I was honestly curious as to whether they were postcards. 

Next time I think I'll stay home...

Give me the gist of the text in a nutshell
<bot>: Went to a Christian gift shop and found a postcard of Jesus being crucified. Told my Christian dad, "Wish you were here!"
