I had to share the first Arlo and Janis, and I figured, well, I can't just share one so I added a few more favourites.
A&J is one of those strips where the characters age. It's not real time like in For Better or Worse, but it's maybe half-real-time. They have one son, so if he seems kind of young, that's an early strip.
I may have mentioned earlier that Arlo can be a tad suggestive and the Comics I Don't Understand website kept comics that might have an adult explanation on the "Arlo" page.
