Kind of unexpected.. but I've been spending a ton of time with my 12 year old son - both DH and DD are away so it is just him and me this week. I'm exhausted (he's a total extrovert and NEEDS people, I'm an introvert so my tendency is "Leave me alone!") but I am so enjoying our time together. I've brushed up on all my 12 year old boy music choices (how many songs can you play that have the word 'fart' in them..) and we've had some really good meaningful conversations. Also, we've started a routine of making supper together, eating in the living room while watching Star Trek Voyager. Not a bad way to pass the time.
I also have to say, single mothers of only children, My hat goes off to you!
