Some questions about the word "Ironic" or "Irony"

A situation isn't generally ironic, a person could be.

Only something using meaning 3 here could make a situation/state "ironic, in the way/fact that it happened":

-------
ironic
 
adj.

   1. Characterized by or constituting irony.
   2. Given to the use of irony. See synonyms at sarcastic.
   3. Poignantly contrary to what was expected or intended: madness, an ironic fate for such a clear thinker.

In that (meaning 3 above) the happenings in your sentences could be seen by some as ironic.

However, I do not think they are. They are unexpected, surprising or coincidental, OK, but to say that it is ironic that they happened, a note of absurd is required, in order to generate the sarcasm (as in the example at 3 above).

Even more, other dictionaries don't even support  the interpretation at 3 in the above, and insist on the sarcasm, which is the original meaning:

--------
iron·ic   

1 : of or relating to irony : containing, expressing, or constituting irony <an ironic remark> <it was ironic that he should enter then>

2 : addicted to the use of irony : given to irony <a very ironic man>

3 obsolete : DISSEMBLING, PRETENDED

Actually, I used the word "ironic" today at work. We were talking to our corporate lawyer about protecting a new product name with a registered service mark, and the lawyer said "What if someone only Xeroxed the front page?" Because "Xerox" is still a protected name, the proper thing to say is "a photocopy," not a "Xerox." I pointed out that it was a ironic that we were talking about protecting our service mark and in doing so he casually violated someone else's mark. It was a contrast to what would have been expected. (Now, if it turns out that one of his other clients was also in the process of getting a service mark registered, that would have only been a coincidence.)
