When using the verbs ‘sit’ and ‘stand’, in particular, it has become commonplace to use the Past Participle instead of the Present Participle. Thus people might say ‘I was sat on the bus when it began to snow’, or ‘He was stood watching the carnival’ – this form is only correct if the passive voice is being used – i.e. as if somebody had placed ‘me’ in a seated position in the bus, or had placed the man in a standing position as though we were children or toys.

If the adverb is longer than three syllables, you might find that the sentence flows better if you put it directly after the verb.
