I didn't kill her. 6let had a blast at storytime for once (MIL took credit).
After lunch with DH I went to run errands. One of which was closing a savings account. The account was in both names. Oddly, they didn't need both of us. Even more odd they never asked for ID.
I was telling MIL this and said "what if I was draining the account to lkeave DH?" Oddest of all MIL replied "I did that once."
