So you expect 1-2 older siblings to hold the whole family down? How are they supposed to pay the rent and other expenses for 5+ people? C'mon nowSomalis in the UK need to rent/move to the same areas and away from madoows and other hateful, violent ethnic groups who want to drag us down with them.
Somalis tend to live in houses with 4/5 people minimum, since most of the post-civil war 'children' are able-bodied adults, there are no excuses for living in the ghettoes. You can certainly afford to move away from these horrible neighborhoods, if you can't, move to affordable cities like the East Midlands.
I'm certain young Somalis in Coventry, Leicester, Nottingham etc, are not worried about Madoows stabbing them.
Stop embarrassing/failing your parents and fix up! Get an education/job and figure out how to afford rent in decent neighborhoods.
Unless you want you/your siblings or your children to act ghetto or get stabbed!
Finally, people are/become what their environment is. If your environment is a pissy, drug dealing, low-life, slum, that's what your mentality will be.
If you show your siblings/children middle-class neighborhoods and culture, that's what they will aspire to be.
