With very short sentences, do I need a comma? Why we use a comma when we’re reading a sentence? Why do we use commas in any sentences though we speak in a slow, pause-in-between statement or all-in-one-go?

The repetition of you obviously changes the emphasis as this is a rhetorical effect or device. Using you three times hammers home the fact that it was you who did this.

I would not use a comma if you omitted the second two yous because I personally try to avoid using a comma to separate what I would consider non-independent clauses ( and cheated on me) though I notice I did this anyway in the second sentence of this answer ( but introduces pauses ). I agree that punctuation, including comma usage, can vary depending on the writer of the answer /

question.

It’s the ‘Google Maps pin’ an “eardrop-shaped marker icon

including a shadow” which is part

of its description found in the patent for the very thing you ask about. In Wikipedia, pin it in Google Maps.

Oops, but the article says “Google

Maps Pin” has been called “a product of pure function that has evolved into a cultural phenomenon”, which assuages

my predilection by more to its function than its name. At least now I know what to call it, as before I was thinking just to say “red bubble thingy” or “red balloony thingy”.

What is a pushpin than a map pin? It’s a generic term than

map

pin (which I wouldn’t use) and more pleasing than any such overlong term as Location indicator, Position locator, etc.

The red balloony GPS position-location marker thingy I got and sent a virtual teardrop with a real tear drop would seem to work. I

find it very interesting, but if I want to do something about it, why don’t you suggest?
