Also, having two small children to keep me busy, questions asked at weekends may have to wait until Monday.
Upon reading the sentence above, my first reaction was "Seriously? Do questions have two small children?" which led me to believe the sentence is flawed.
Is that a valid ground to question the correctness of the sentence or people don't really give a darn and use these kind of sentences anyway?
Yes to both questions.
(The sentence is flawed but in real life who gives a damn? The meaning is clear.)
