Actually you will find that areas like East ham, ilford, seven kings - were Sikh majority areas till the mid 90's .
Then when the Pakistanis saw an opening to buy some of (Sikh or white owned) businesses they just spread like wildfire.
The same was for southall - till around 1991.
Issue there is most of the leases of the shops are in Sikh hands, in east London its practically all Pakistani / Bangladeshi.
Some of my rlatives in forest gate were offered straight cash prices for their houses - this is around 1992/3.
Fault lies with some of our people - they just saw the financial incentive - now they regret it.
Ask your self does a Musallman sell to a non muslim, especially a Sikh ?
Pre-emptive war is never a good idea, maybe these aliens could assist us in some way. But if they were going to be the first to discover aliens, many people throughout time have already claimed such things. Dhan Dhan Sri Guru Nanak Dev Ji went to other planets.
You are in 7th grade, and expecting what from a crush? You just reached puberty most likely, so almost everything your feeling is probably just hormonal. At your age you'll probably have 100s of crushes by the time your done with your education, you just had your first crush later than most people. In the very best case scenario, she might think you're attractive as well, but if you are going to be having relationships, it won't really help any of you, since this age is hormonal changes.
If in the future she does become your future wife, that will happen then with Guru Sahib making it happen, but for now, focus on something that makes you happy, (and if you can't control your feelings, try not being to close to her).
Do your Bhagti and Amrit Velas, some Seva and grow with Guru Sahib. 😇
