I know that the meaning of this phrase is often context related, but I'm not really sure when or in what situations it can be used. So, I'd appreciate it if you'd just give a context as an example yourself.
(I'm always looking to improve on my English; so, I'd greatly appreciate it if you would point out any grammatical mistakes I've made in describing my question)

The first thing that comes to my mind would be if you see someone carrying lots of stuff, and approaching a door - one might jump in front of them and open the door for them.
Similarly, one might see a person about to pick up a heavy load, and say this before helping them - either by sharing the weight or by picking it up yourself.
