This shouldn't be understated. I think, as you grow older, you can't be bothered with the hassle of life that many of us once got involved in.I like it tbh. Turned 37 this year and as I get older I feel more and more comfortable with myself and at ease with life. I have a great missus, two lovely cats and a nice house and I wouldn't trade it for anything. Even if it meant I could give away my bit of belly and slightly wonky knee
It's the simple things: enjoying time with the wife and children; building a home and feeling genuinely pleased that you're building something together.
I have a few mates who don't have children and/or still try to live the young life; when there's hassle between the group, you can tell they feel aggrieved etc.
I just let it pass me by: why be offended when someone doesn't turn up? Or having a go if someone isn't invited?
