I feel like I have to jump in here. The worst clients I've ever had (and also the worst clients other businesses I've worked with have had) are the ones you do charity work for (family included). When people aren't paying for something, they place absolutely no value on your time, and without fail the relationship will sour at some point.
I'd charge a friend or charity a lower rate that they can afford but strategically set such that their budget (and amount of work they get) seems finite to them. Forces them to come up with their plan and execute, instead of "yeah that's nice, but my friend said THIS would be a better idea...can you just redo the whole thing??" Yes, you can say no, but like I said if there are expectations on either side, it can sour the relationship.
I'm with you. I lie about what I do to half my friends to avoid their hurt expressions when they find out that I'm not going to bunker down for the next 2 weeks writing their app for free.
