The husband found a wide crack in his wall and taped it up so no one would accidentally get hurt. They discussed the possibility of damage to the foundation caused by a previous leak and agreed to call a professional to take a look.
human
Hey, I found a crack in the wall today.
gpt
Oh no, is it a big one?
human
Yeah, it's quite wide and goes all the way through the wall.
gpt
That doesn't sound good. Did you figure out what caused it?
human
Not yet, but I taped it up so no one would accidentally get hurt in the meantime.
gpt
That's a smart move. We should probably call a professional to take a look at it though.
human
Yeah, I was thinking the same thing. Maybe it's related to that leak we had last month.
gpt
Oh yeah, I forgot about that. It could have caused some damage to the foundation.
human
Exactly. I'll call a contractor to come and take a look at it tomorrow. 
gpt
Sounds like a plan. It's important to take care of these things before they get worse.
