One of the virtues of parental investment er theory I would say is that er it's particularly sensitive to female interests in, in  in sexuality and nobody who knows me or has read er my works would, could possibly suspect me here of fashionable feminist prejudices er so I don't say this because I think this is what people like to hear, but because I happen to think it's true, I'm afraid I'm one of these old-fashioned and you may think stupid people who believe that you should er say things cos you think they're true, not because you think er it's what you think want w want to hear or if you say it, you'll be accused of sexual harassment by a lecturer as I was last year.
