Hand 1:
As dealer, none vul, RHO opened this hand. Not an unrealistic idea, you might say - there's a perfectly sound 2♦ rebid, or I can raise partner's ♥ suit. However, the character in question decided that this was a perfect 3♦ opening.
Hand 2:
On this hand, none vul, my partner dealt and opened 1♣ (at least 2; fairly simple 5-card-majors system). This hand doubled to show "at least an opening hand", and neither partner nor I expected this when she was silent throughout.
Ah well. It was good to get a game in between work and sleep.
