I think your problem isn't relegated only to the BB, all hammocks seem to be magnents & prone to "theft" by our loved ones.
AND, I don't have a BB, but still am always trying to get another hammock put into the budget:
"After all dear, I only have 3 full set ups, & I hate odd numbers."
"But what if someone wants to borrow one?"
"The next one is for you!"
"But my newest one already has over 100 nights in it! What if it's worn out???"
In case you are wondering, she didn't buy any of those reasons.
After over 30 years of marrage, she is mostly immune to me & my obsessions.
