Answer:
bare or time.
Explanation:
People often use the other "bear" for disappointment, if thats what you meant to put.
As an example, "I can't <em><u>bear</u></em> to see this", or, "I know that person, but I can't <u><em>bear</em></u> to talk to her.".
"Bare" is used to explain nothing there, like another word for "nothing"
As an example, "Don't walk in here with your <u><em>bare</em></u> feet". The word "bare" is describing "feet", saying that there isn't anything.
Time can possibly be an answer because, as an example, "What's taking so long? Your wasting <em><u>time</u></em>", or, "Well, what do you know? Look at the<u> </u><u><em>time</em></u>.", and, "It's <u><em>time</em></u> to go!".
If I'm right, its probably going to be....time.
If you typed in the wrong "bare", its probably, "bear".
