I've noticed within the past 2-3 decades that brothers have not traveled to various destinations with sisters and/or families.
Myself with my own 2 sisters (bio/spiritual), 3 cousins, and 4-5 friends usually travel once a year during the spring and summer months to a number of places, whether it be via bus, train or plane. The travel groups [there are 3 which are commandeered by some older sisters and their own bio sisters, daughters, and granddaughters plus a niece or two)] which total about 30-40 persons travel regularly during these times of the year. Although there are a great amount of females on these trips, there are hardly any adult males in attendance; the only males who are seated with the group range from age 5 to 12 approximately--these young boys are 2-6 in total--and once they reach high school age, that number dwindles from 1-0!
After witnessing this pattern, I asked my two male cousins who are in the org and three other brothers, whom are close to my family. They all expressed, in their own words, that "brothers are not interested in shopping or going to a lot of places that sisters like/fancy to go/see". I became confused by those words--especially since I see groups of MEN and BOYS in so many other groups (no doubt NON-DUBS) travelling and having a great time/fun with females (no matter what age range) in their riding parties. {Hell, my above-listed family and friends spoke about a large car group of people, which we saw during a recent trip--racially mixed with men and women, children plus pets--shopping, dining and having a great ole' time!} We all could not believe it!
I asked the sisters who were the trip leaders about this. They commented that "a number of brothers act like, unless they are getting married to a sister, they won't want to be in the company of other ones" and "Some brothers feel more comfortable associating with other brothers. They think that sisters are not interested in basketball games, pool, certain movies and the like. So, they decline when I ask them to go on my trips!".
Furthermore--if I could add to this topic--I attended a year and half ago a formal. This event was given by three married sisters. The invitees in attendance was mostly female and very, very few males (ratio: 90% female - 10% male). The males there were the marriage mates of the hostesses and their daughters plus nieces and a toddler or two. As usual, the majority of women (mainly sisters) who could dance, danced with one another.
Again, what is going on here with the org? Mysogyny--or are some of these men involved in things, which on the other hand get them in a whole $%^* load of trouble in private while the women are globetrotting? (Sorry for my rant again) Oi vey!!!!!
