[EX Q]: Consider this quote from Mark Twain: 'Familiarity breeds contempt - and children.' Does it mean having children is a bad thing? Could you explain what the children imply here?.
[EX A]: Two thoughts are run together: Familiarity breeds contempt {knowing people very well lets you see their faults} Familiarity breeds children {physical familiarity between the sexes leads to children} Hence Familiarity breeds contempt and children. A similar example of this particular way of playing with words (called Zeugma) is: 'You are free to execute your laws, and your citizens, as you see fit.'

[EX Q]: Is there a way to indicate that somebody is your girlfriend without using the possessive term my? I think saying She/He is my partner/other half is OK for married people, but it doesn't feel right for girlfriends and boyfriends.
[EX A]:
There is nothing wrong with using my. Saying my medical appointment does not mean the medical appointment belongs to me, but just that it is connected to me in some way. Stick to my for there is no alternative which expresses the idea succinctly.
