Unfortunately there are people that prefer other people do things for them and they begin to create a patsy list of people they can "use" when they want to get things without doing it themselves. There also are people that genuinely don't know how to problem solve as it could be that they never learned how to learn too. You always have a right to say, "sorry but I am not very good at giving you the kind of advice you are looking for". After a while this person will get to know you are not someone they can lean on for help. You always have a choice and can say it nicely like what I just put in quotes.
