Hello there, I would like to learn about Karachi. 
 Sure I can help with that. Karachi is the largest city in Pakistan and the capital of the province of Sindh. 
 When was Karachi founded? 
 I do not have that information,but it is located on the coastline of Sindh province in southern Pakistan. 
 What body of water is it on the coastline of? 
 Its is along the natural harbor on the Arabian Sea. And to the west of Karachi lies the Indus River flood plain. 
 Do you have any interesting historical facts? 
 I do not have that information currently,I can tell you that the city is home to a large number of Hindus and a small community of Zoroastrians. 
 Tell me more about the Zoroastrians please. 
 The citys inhabitants are referred to by the demonym Karachiite in English. 
 How did they get that name? 
 I dont actually know how that was originated,but you might find it interesting that Coastal mangrove forests grow in the brackish waters around the Karachi Harbour and then farther southeast towards the Indus River Delta 
 That is very interesting. Is there any other fact you find interesting before I end this discussion? 
 Karachi is considered to be Pakistan's fashion capital and hosts a fashion week since 2009 
 That is interesting. Thank you for the dialog. 
 You are welcome
