"When since introduces an action or event at a point of time in the past, we can use the past simple or present perfect after since and the present perfect in the main clause:
They haven’t received any junk mail since they moved house.
They haven’t received any junk mail since they’ve moved house."
Was stunned to see Present Perfect justified like that after since in this context. Is the latter example really possible? Have been correcting students for years... I've always thought Present Perfect after since is only used when the state lasts to include the present moment:
... since I've been/lived/had/loved/known, etc.
Thanks in advance,
