Thanks for this thread -- this is so great!
I'm a single dad, mom left 4 years ago, and I'm raising my DS15 and DS12 alone. I cherished them anyway, now even more. DS15 has had a lot of problems with his mom, DS12 has had an easier time, and thankfully both are doing ok now, although DS15 doesn't spend much time with her.
I'm a pretty upbeat, positive person, good sense of humor, sometimes a clown, but my kids will sometimes get on my case that I need to lighten up, not always be so serious, and not just work work work at home. That gets my attention, because I don't think of myself as serious -- but I think just the volume of work a single parent has to do can take control of how we spend our time at home, the effort and stress in working full-time and raising teenagers can affect our sernious-ness -- and their comments to me are always a good wake-up call.
I really try hard to focus on them when I'm home -- I know I don't get it all right all the time, but I'm trying -- but I love them a ton, try to tell them with my facial expressions and actions, and make sure I tell them in words so much it makes them sick!
Thanks for a great thread -- lots of great insights and advice!
