I'm thinking of throwing away the water bottle my husband has been looking for.
Why do you want to throw it away?
I accidentally broke it by stepping on it.
It's not right to lie to your partner. I'm sure if you tell the truth he will be okay with it.
I know, but I don't think I'll be a big deal.
I can see why you think it wouldn't be a big deal. But even though it's just a water bottle he could be really stressed out about looking for it. I think you'll feel better being honest with him so you no longer have to hide it.
