So yesterday morning Hubby and I slept in a bit. Thing 1 was still at her friend's house, and all was quiet at ours. Too quiet. Hubby got up and went searching for T2 who, it turns out, was outside, still in her jammies, playing with the neighbor kid. We had a little talk about leaving the house without permission and without appropriate clothes.
Then last night around 11pm, T2, who had been fast asleep, came downstairs crying. She had chewing gum in her hair, on her arm, and on her jammies. She steadfastly denied taking any gum into her room, and insisted T1 had left it on her pillow. While I cleaned T2 up, Hubby questioned T1, who denied any involvement. We decided to leave it for the morning. I interrogated them both this morning and soon got the culprit to crack. The result? T1 will be cleaning T2's room for a while.
