If Theresa's daughter is my daughter's mother, who am I to Theresa?

How about Theresa's ex-son in law that's too lazy to get a job and has no more ambition than to sit around and play video games all day, won't pay child support and gambles and drinks away whatever money he ever gets (usually by nefarious means)?

What about Theresa's son in law?

The choices are all female. Assuming the correct answer is there, then you must conclude that the one asking is female. It's all very logical.

Bewley Steve I think JRE was joking....

Bewley Steve what the crap? Who's having a hate filled rant?? I think you deserve the credit for hateful spew.

you are assuming the person asking the question is female. the answer is not enough information given.

The question was strange, but the comments were the authentic entertainment.

Took a while but I got it.

I'm Theresa's son-in-law.

Worded incorrectly. Had it said, "what is Theresa to me", then THAT would be daughter. The answer to the question as it is laid out, is.... MOTHER. I don't normally complain but this answer gave me my only red dot in 10 answers and was, incidentally, the last question. Thank you, author.

Jim Hochstetler, why give it yet another chance? I'm sure you will be sorely missed.

Det stämmer minsann inte

Peggy Tinsley, me too, Peggy. It means we are getting old.

One more question like this will be an excellent candidate to persuade me to pay no further attention to quizzclub.

It doesn't make sense and I disagree with the answer!!!

Janet Reno Eveland, Did you drink too much coffee today ??????????

You are normal. Peggy Tinsley,

It is not trivia. I didn't even think about it. I just clicked to came here to protest and keep on in the game hoping next question is indeed worthwhile to think about.

Ranajit Bhattacharyya. What? And Why?

Could be son, or son-in-law or daughter-in-law as well. :)

That one gave me a headache.
