When you are performing an action on yourself, rather that on someone else, then the verb you are going to use is a reflective verb. For example, <em>to tuck yourself in </em>- this means that you alone managed to tuck yourself in a bed, rather than have someone else do it for you.
Reflective verbs are always followed by a reflective pronoun, such as myself, yourself, himself, etc.
A direct object is a word or a word group that follows an action verb and is the direct receiver of the action expressed in the verb. Most often, the direct object is a noun or a pronoun.
