Not really needing advice, just curious to see if anyone else had experienced a similar thing 
So, I had left my son home, as I was out doing some errands. I was gone for about two hours max, nothing special.
When I got home, I walked into my living room to find my 13 year old cuddled up with his 15 year old girlfriend. I didn't disturb them, nor did I truly care. I went about my usual business.
I found it quite funny, actually. Eric is usually quite timid, and the few times she's been over, they would keep it very tame, maybe my husband and I just intimidate them 
If anyone else has had any encounters similar to this, feel free to share!
