Some verbs do not usually take a reflexive pronoun, although they may in other languages.
We'd better hurry, or we'll be late, NOT We'd better-hurry-ourselves. Shall we meet at the cinema?
I feel uncomfortable. Just try to relax.
Some of these verbs are: afford, approach, complain, concentrate, decide, feel + adjective, get up, hurry (up), lie down, meet, remember, rest, relax, sit down, stand up, wake up, wonder, worry
We do not normally use a reflexive pronoun with change (clothes), dress and wash.
Daniel washed and changed before going out.
But we can use a reflexive pronoun when the action is difficult.
My friend is disabled, but she can dress herself.
