Yep... That's what I kept saying... to myself.

Doesn't work like that.

Consider this if you use the <br> keyword because you didn't take the time
to be the expert with Frame, and that's the only truth there is to the
matter. Convenience will not buy you points. Um... Trust me. I promise.

Then...

What happens later? Are other requirements using broadcast or unicast?
Why? Why not? Are you sure?

How many point did you really lose? 2, 3, 10, 20?

Hey it's your $1400.00 lunch, enjoy it any way you want.

Better not to go in the lab and expect that it is going to be with or
without the <br> keyword.

Some will call this an asumption on your part.

Proctors may take this as an assumption this type of candidate needs more
time to clear up these assumptions before winning the digits.
