Jesus Christ.
it's a parable, he means "older people", why is it, when it's a guy it's ok but if it's a woman it's sexist.
sure, his words could be "parent" but:
1) it doesn't flow
2) it's something everyone can relate to
3) we're from a generation of the largest number of single parents (which are mostly women)
4) it's an adorable method of wording, not a derogatory one.
for the love of god can people stop harping on about sexism, sexism exists and you just hurt the cause when -every- time soemone says "woman" you just jump to the defensive and start slandering everyone.
Don't assume malice, your life will be easier.
