Married people have been posting here for as long as I've been part of CC.
Some of them give really wonderful, helpful advice. I always mention this one, but there was one year when Fenner had a thread that went something like, "What Valentine's Day Is Like When You're Married", and she outlined her schedule of spending time with her husband and caring for her family. It wasn't all chocolates and roses and moonlit dancing.
Instead, it was a really down-to-earth look at what married life is really like, which helps reminds us singles that getting married isn't all rainbows and sunshine like we sometimes think. People like Fenner remind us that the grass on the other side might look greener, but it still has to be mowed and maintained.
MissCris also has an exceptional talent of making any ordinary day with her family sound like a story. I also enjoy mailmandan's quips about traveling with his wife, because I hope to do that someday if I find someone. (I know I'm forgetting some other regulars here who are married... Please know that we appreciate you.)
Most of us here in singles welcome and enjoy compassionate, realistic, helpful advice from our married friends. Who better to ask than those who are living it themselves? If we all want a marriage that lasts a lifetime, it's important that we occasionally hear from someone who's been married their entire life how it's done.
The only time I've seen eyebrows raised are if someone married make assumptions (that our lives are incomplete or we're lacking because we're single), and/or starts to give unsolicited lectures (on what we should be doing or how should be going about finding a spouse.)
P.S. Skittle, this is also an invitation for you to post in Singles more often!!
After all, people often say Singles has some of the most fun and interesting threads. We have arguments like anywhere else at times, but mostly, we all kind of "hang out" and get to know each other and keep each other company, which is why I keep coming back.
