Some verbs are not usually used in the progressive tense even when they describe an action that is happening right now. These are called ‘non-action’ verbs, or Stative verbs.
Stative verbs describe emotions (love, hate), mental states (remember, believe), wants (need, prefer), perceptions (hear, see), appearance (look, seem) and possession (have, own). Avoid the Present Progressive when using these verbs.
