Oops. The webpage cut out part of my response. Right after I wrote
Hacer + Infinitive, the second paragraph contains;
and here I quoted from the lesson:
.."There is a tendency to use indirect pronouns me,te,le,nos,os,les when the verb in intransitive. However, if the verb is transitive, we usually use direct object pronouns me,te,lo,la,nos,os,los,las.
That's where I asked if this is misprint, or is referring to common mistakes that we make?
The remainder of my comment got posted correctly. Hope that my points are more clear now.
