I think I have been through most of the poll options above over time.
I started with "Yes, gladly", but have found that my best case nowadays is "Yes, but at great cost to my eternal soul". It does depend to some extent which member of family/friends I'm dealing with. My best friends and favorite family members DON'T ask for or get any tech help. Try that simple check for yourself. Doesn't mean I don't do anything for them, just not that dirty techy stuff ;-)
In most cases nowadays, it is actually "No" in one form or another. Let's not be dishonest with each other, "I feign ignorance" is a reflection that you can't say that word "No". In other words, you prefer to lie rather than offend friends or a family member.
I must say I was staggered by the huge vote for "Yes, but at great cost to me". Clearly, you want to say No, but can't or won't do it. I hope that the friends/family understand that it's a big favour you're doing for them; it's not something that is necessarily easy, nor that you want to do!
Anyways, as I get older...err, I mean more mature, I move further down the "No" tree. Goddam kids better stay off my lawn too!
