I’m a good broodmare?

Is that a compliment or an insult?  I suppose it all depends on who it’s coming from — in this case, Bob Smith, owner of Netherwood Acres, after I told him I had my third child when I was 41.  Bob’s 84 and still riding, still jumping cross-country courses.  I don’t think he was coming onto me, but he did tell me that I was “cool” and warned me not to tell his wife, Lisa, that he said that.  Lisa’s at least 30 years younger than Bob, but my guess is that her broodmare days are probably over, too.
