<human>: This weekend, my fiance, her parents, and myself went to Vegas to look at hotels and chapels for our wedding next year. Over the weekend, we had my fiance's 20 year old brother watch our two chihuahuas. We were gone for just about 2 days. Last night on our way home, when he went to walk the dogs for the final time, one of them got out of its collar and ran away. The only way it would have been able to get out of its collar is if it was tugged on excessively in a direction that the dog did not want to go. This particular dog is a rescue and does not like crossing any sort of paved street since he was hit by a car before we got him.
Instead of searching his apartment complex for the dog, he decided that he would just go inside and smoke weed instead. Since we were still on our way home, we had no way of helping the search. We finally arrived back in Arizona about 5 hours later and started searching. It took us 3 hours and thankfully we were able to find him. 
Since I was with his parents when this happened, I had to hold my tongue even though I knew he was in the wrong. 
My question to you guys is have you ever been in a similar situation where someone close to you, family member or in-law, did something so messed up and instead of helping, they did the complete opposite.

Give me the gist of the text in a nutshell
<bot>: My fiances brother lost one of our dogs after he slipped of the leash. Instead of searching for him, he went inside and smoked weed. I was with his parents so I had to hold my tongue about the entire thing.
