Present simple, continuous, perfect and Past simple, continuous

I ( see ) this film this week.

When I (enter) the kitchen,I (see) that my mum (stand) at the table and (cut) some mushrooms.

They (visit) their grandparents now.

Every evening my family (gather) together and (discuss) our problems.

When you (come) in, my sister already (clean) her room.

She (write) a letter at the moment.

My boss ( not drink ) coffee very often.

My friends (not watch) this video yet.

When you (come) in ?

My dad (fix) his car by that time yesterday.
