|An alley in the Beacon Hill area of Boston, Masachusetts|
You might say, "There's a garbage can up my alley," or "There's a bunch of trash up my alley." Alleys or alleyways are tiny, narrow paths or passages between buildings. They're usually dark and dirty although once in a while you'll run into a clean one like this alley in the historic Beacon Hill neighborhood in Boston, Massachusetts.
- ONCE IN A WHILE - sometimes
- RUN INTO - find; meet; come across
The idiomatic expression "UP YOUR ALLEY," however, has nothing to do with a physical alleyway; it has more to do with someone's interest or expertise. For example, if you're a web designer, then designing web pages is UP YOUR ALLEY. If you're a car mechanic, fixing cars is UP YOUR ALLEY. If you're studying film, then perhaps acting or directing or film editing is UP YOUR ALLEY. You get the picture.
- YOU GET THE PICTURE - You get the idea; you understand
