Wording

The ordering of words is important.  Simple differences in the wording and order of a sentence can completely change its meaning and how it comes across to people.  Let use the first date example.  Imagine the reaction of a woman when her date tells her he "lives with his mom."  She obviously thinks he is a loser with no future.  Now what if the man had said, "my mom lives with me."  The woman likely thinks he is a nice, sympathetic guy for taking in his mom.  Both statements tell you that the man and his mom live together, but neither actually specify who owns the house they live in.  Now if the man on the date wanted to admit who owned the house, he could say "I live in my mom's house" to the same reaction as the first statement.  But, if he stated that he lived in his mom's house differently, say "I moved into my mom's house."  He never specifies when he moved into his mom's house (whether at birth or recently).  With the assumption that the man on the date is not a teenager, this statement is usually taken to mean that he moved back into his mom's house, possibly to help take care of her or something.  Simply rearranging the words gives the woman a very different opinion of the man.  Weird.
