It is the awkwardness of the situation. Exactly why I (female) only play with my twin sister. Like your wife, we both have serious anxiety and stress about playing with strangers. The very first time I tried a Strike in D1, I got a message saying "you are the worst ever." I responded back and said, I had no idea what to do or what was going to happen. He or she did come back and say its all good...but getting that message made me feel bad (I mean it wasnt the end of the world because I am prolly old enough to be the kids mother, but still) :-). We are not the best players, we used to run through Night Falls Strikes just because it wasnt matchmaking and some days we would die 10 times, but we didnt care because we had no one depending on us to get it done (super stressful). Yes its nice to finish something, but some fireteams out there can sure suck the fun out of the way we like to play. Oh and one more thing...I also found that if you have your own terms for items or supers, that is sometimes frowned upon as well. Example: blue ball, purple ball, walrock "sparkles", little monsters, yellow monsters, gun, hat, sleeves, pants etc. :-) Glad there are so many people like us out there.
