Yesterday we were visiting my uncle.
Why were you visiting your uncle?
We had heard that he was sick
It is good that you are visiting your uncle when he is sick. Family is important and it is good to support them in tough times.
To be honest my uncle wasn't that sick. We just wanted the free beer and free food that he always provides.
In that case, it sounds like your uncle is an amiable person, and that you should visit him more often.  If he is so eager to have company, you shouldn't have to worry about him being sick, just arrange for occasional visits.
