We showed some good judgement early on:
We were playing 2/1 so June created a game forcing auction with her initial response. I then bid out my distribution and finally made a quantative 4NT bid. June naturally refused with her minimum, non-fitting hand. With hearts 3-3, diamonds breaking and the ♠A onside June made 12 tricks for a reasonable score when others got the spades wrong.
Edit: hand corrected as per Alan's comment. Bidding 6♦ is excellent but I don't think it's clear for June to raise diamonds with such a poor suit. However she would have shown the support if accepting the slam try.
