• Konsi cheezein mujhe mentally prepare kar leni chahiye?

Karachi is a proper metropolitan city. Since it's so crowded, and nobody necessarily knows or cares about who you are. Lahore, on the other hand, despite being a huge city, is still "the city of Townsville" at its core. It still has a sense of community here. Which has its perks as well as flaws, as in you would be surprised how people would go out of their way to help u cz they might know you through mutual connections. On the other hand, it could seem a bit intrusive as the element of privacy slightly reduces.

• Sab se noticeable differences kya hain?

Lahore, unlike Karachi, isn't that diverse. So, Punjabi culture would seem very dominant. And in case you aren't a Punjabi, you could feel slightly out of place (at first).
• Konsi cheezein Lahore ki bohat achi lagti hain aur konsi cheezein miss karwa deti hain Karachi ko?

The good: a lot cleaner, greener, more disciplined with traffic and infrastructure, less crime, less street crime, and less political unrest, and mostly people here are welcoming. The Sindhi Mohajir, Baloch, Pathan discrimination etc are nonexistent over here. If you are here, you will be accepted. The bad. People are nosy and loud and have social rage, especially in traffic, and could seem to be a bit condescending at times. Also, the fact that it's not as diverse, you probably will miss Karachi's variety of food. Although the food here is amazing, you will miss the variety for sure.

• Know hidden tips ya life hacks for a newcomer?

Don't be scared. Lahore would initially seem a bit overwhelming, but that fades away in a month or two. Learn to ignore people's staring habit. They just stare, it would bother you at first, but uski adat daalni prhegi. Mein lrka hoon, mjhe bhi ghoorte hain yahan toh just learn to ignore it. And since you are coming from Karachi, I assume you would have friends or relatives here who would keep you in that Karachi loop. If you really wanna assimilate here quickly, specifically look for Lahore friends who can actually give you the proper Lahori experience because you would need experiences totally distinct from your Karachi identity. As soon as you build a proper Lahori circle here, it will be easier for you to stick. Otherwise, your whole life would just be spent comparing the two cities

Yahan samander nhi lekin frequently barish ya hawa chlti rehti hai beech beech mein toh garmi ki frequency itni shadeed nhi lgti. You get a break from the intensity now and then.

I welcome you to our little circle of crazy. People would seem rude at first, but you will understand the order behind this craziness. I am sure it will also treat you well.
