<human>: So this weekend I went to go visit my girlfriend at her parent's house. I decided to sleep on the living room couch during my stay. Last night, (3AM today to be exact), the dogs kept scratching at the backdoor. My girlfriend, her parents, her sister and her baby were all asleep and I wasn't sure if they wanted to leave the dogs out in the yard for the whole night. The weather was getting nicer so I thought it kinda made sense but they kept scratching and whining so I get up and walk to the door. I grab the handle, turn it, pull the door and I immediately regret it. All of a sudden a security alarm goes off, blasting at full volume, at 3 in the morning. I facepalmed so hard as I listened to an automated voice on a loudspeaker say "A DOOR HAS BEEN OPENED. AN INTRUDER HAS ENTERED. THE POLICE HAVE BEEN CALLED. PLEASE LEAVE THE HOUSE IMMEDIATELY!" It's repeating that along with an alarm noise going off. I decide to walk to her parents room (also on the first floor) to try and explain the situation. Their door is ajar but all the lights are off and I'm afraid of walking in because I didn't want to be mistaken for a potential intruder. I'll never forget what happened next. Her dad rushes out, shirtless, one hand holding a blanket wrapped around his lower half with a surprised look on his face, something straight out of a comedy flick. I try to yell over the alarm that I opened a door and luckily he was able to hear me even though we were right next to the loudspeaker. He puts in the code to shut it off and calls the police to let them know it was a false alarm. The next morning I tell my girlfriend (her room is on the second floor) about it and she didn't even notice. I'm not sure about her sister and the baby (also sleeping on the second floor) but for the most part it didn't seem like that big of a deal. I'm just glad I didn't get knocked out by her father for possibly thinking I was a burglar.

Summarize the given text in a few sentences.
<bot>: I open the backdoor to bring in my girlfriend's dogs, who were out in the yard, at her parent's house and end up setting off a full scale security alarm at 3AM.
