True, hypocrisy at its finest.
However, there is a level of stringiness that makes the family look very bad. From what i've seen even the guys side of the family are very aware of this. The only families that i've seen that have encouraged their sons extreme stringiness were the reer bado wayward types. Yes, they might tell their sons to be frugal, but there are levels to this. Most times the guys in our communities get help from parents and close family because they know how costly weddings are. I've even seen mother-in laws push their sons into having big weddings! Somalis love competing with each other.
Also, we are a group of people that don't like to be disgraced in front of others. For instance the nikaah (the wedding ceremony/ walima) I would say is the most important. That is when all the odeys come together and imagine this man wants to spend less than $5k! I think even his family will laugh! The venue, the payment that needs to be given to the Sheikh, the food ect. In my area pre-Covid Nikkahs tend to be big affairs because of the barakha of feeding people ect, so being frugal when it comes to that definitely will give you the side eye!
