[Grammar] ‘come along’ VS ‘go along’

[northpath]

There are two sentences from a good dictionary:
1. Wait for me - I decided to go along too.
2. I’ve never seen a rodeo – do you mind if I come along?
Why in the first one is used ‘go along’ while in the second ‘come along’?

In sentence 1, the speaker and interlocutor are joining a group. Most likely, neither is leading the group in any sense.

In sentence 2, the interlocutor is somehow taking responsibility for the group; driving them somewhere, for example.

Questions require subject-verb inversion. Ask Why does the first one use "go along" while the second uses "come along"?

Sentence 1. doesn't sound right out of context like this. Which dictionary is it from?

 

[northpath]

I can’t find the source of the first sentence. These are exact sentences from the Macmillan dictionary online:
He’s going to New York tomorrow and I think I might just go along too.
I’ve never seen a rodeo – do you mind if I come along?
The question remains the same: Why in the first one is used ‘go along’ while in the second ‘come along’?

I answered your question in post #2.

Also please read the last sentence in that post to help you compose questions correctly.
