Subject: Re: brkb, short calls the hard part.
Thanks, but they are 8$$, not a trivial sum...

Then another good choice to consider: buy them back, but then immediately sell new ones at a longer date. Depending on the strike you pick that will very likely be for a nice cash credit. That way there is pretty much no chance of exercise and you can kick the can down the road, giving your thesis time to work out, and also improving the breakeven on any exit if they are exercised.

The modest downside is that the ones you own, being short dated and very close to the money, are probably eroding in time value (to your benefit) very rapidly right now, which is what happens as the expiration approaches. So the more you want to avoid exercise, the more you have to give up a high rate of return for a short while. (Roughly speaking, expect the annualized rate of time value return to be proportional to the inverse of the square of the number of days remaining, other things being equal)

Lots of ways to handle it, depending on what else you own, how much you'd like to avoid their being exercised, and how long you are prepared to wait for it to work out.
