Re: conjunction But & and!
I don't have a sister but I have one big brother. He studies computer sciences and lives with us. My brother has his own business but doesn't have any kind of job. I have 3 uncles; two of them have their own businesses, and one has a government job. One uncle has an electronics shop and also offers home delivery services. My younger uncle doesn't have a daughter but has two sons. My elder aunt doesn't have a job but offers housekeeping services.
I think I have narrowed your uncles down to a mere three in total; I hope that is correct. You need to review the third person singular present tenses, Farhaj.
