We should say, _I was at home_ yesterday.
+3. Do not use the preposition _of_ with a verb that requires an
object.+ The noun cannot be the object of both the verb and the
preposition. As, for example:
He does not remember _of_ seeing you.
Do you approve _of_ his action?
_Remember_ and _approve_ are both incomplete verbs requiring an object,
and the nouns _seeing_ and _action_ are the objects of the incomplete
verbs _remember_ and _approve_. The preposition _of_ is entirely
superfluous. The sentences should read:
He does not remember seeing you.
Do you approve his action?
Other verbs with which we commonly use the preposition _of_ in this way
are the verbs _accept_ and _recollect_. As, for example:
Will you accept _of_ this kindness?
Will you try to recollect _of_ it?
These sentences should read:
Will you accept this kindness?
Will you try to recollect it?
