Jealousy is a weird thing. Some couples stoke it and others don't let it even start. I recall a guy getting noticeably jealous when I interacted with his girl at a bar while I was still out on the road. I think I was getting dinner after a day wasted waiting on replacement circuit packs to arrive. He said something snide to her, but I can't recall what.
I looked at him and quietly asked if he really thought I had a chance with someone as pretty as her. I asked him to look at me and seriously think whether I had any hope in hell for an attractive woman to ever reciprocate. I asked him whether he thought a fat ass enjoying the only female social interaction I'll get in a month or two was something to get jealous over.
I told him to trust her more because she chose him. Because even at last call, even with their glassy eyes, and a belly full of bad decisions, not a single person has ever chosen me. The bartender was within earshot and gave me a fistbump. I remember she had an old bead bracelet and a bass clef tattoo just behind her knuckles. She comped me a beer to go with dinner. I drank it with a smile even though her expression bled of pity for me.
The tension between the couple was a lot better afterward. I wrapped up dinner early though. They felt the need to try to interact with me after that and all either could muster was small talk.
Edit:
Ah crap I rambled on again hahaha
