It's a great feeling knowing that my possible secondary (I'm his possible tertiary) and my primary get long awesomely! They have a lot in common & get together Friday evenings, along with a few others, to play D&D 4th ed.
We'll all have family picnincs together a couple of times during the summer and bring whomever with us. I get my fill of ankle biters at their place and then come home and enjoy the relative peace and quiet of teen agers, lol. He comes over here once a week, usually, and enjoys the total peace and quiet of no kids in residence, no crying, no "Poppaaaaaaaaaa!!!!!!!!!!!", etc. Cuddles, talks, movies with no one else talking (dig at my boyfriend, btw, lol).
*sigh* I can most definitely understand why some folks are drawn to poly.
