I've sometimes gotten into small arguments with my parents. A bit of back and forth. While it's easy to carp, condemn and criticise, at the end of the day they still put in the hours. I haven't admitted to being wrong, but I know I am, once I let off some steam.
I spent $1600 on a litecoin miner like a year ago which is now worth like $80. Didn't make anywhere close to the cost, plus it was stolen by a remote host I was trying to use after 4-5 months
