progressive tenses with always

We can use always with a progressive tense to mean ‘very often’.

    I’m always losing my keys.
    Granny’s nice. She’s always giving people things and doing things for people.
    I’m always running into ( = ‘accidentally meeting’) Paul these days.

We use this structure to talk about things which happen very often (perhaps more often than expected), but which are not planned. Compare:

    When Alice comes to see me, I always meet her at the station, (a regular, planned arrangement)
    I’m always meeting Mrs Bailiff in the supermarket, (accidental, unplanned meetings)
    When I was a child, we always had picnics on Saturdays in the summer. (regular, planned)
    Her mother was always arranging little surprise picnics and outings. (unexpected, not regular)
