One thing I've learned about doing business is that being too friendly with clients can put into a very difficult position you start off trying to make them comfortable you get just with them give them instructions without charging overlook late payment because you don't
want to make this uncomfortable but before you know.
If they are treating things that should cost extra as part of the original deal and the funny thing is when you finally try to send value you are the one who certainly seems because be friendly with your clients no problem but make sure they understand that you are running a business not doing favors for free.
You can be a good person i still insist on being paid properly for your work you can be friendly and nice and still stand on business when the right time is closer so be you and do yourself.
