So for some context; a few years ago I let the parents know about my intention to buy a motorcycle and it didn't exactly go down smoothly however it went down. Went out to purchase gear, some resistance but overall approval. Arose early one Sunday morning to go and collect the bike, to be told I was not getting the motorcycle under any circumstances. Licence expired, etc. A few years have passed now, and this Friday represents my 21st so I figure it's not a bad time to bring the news up. I purchased the bike in Mid-November and it has been a complex game of covering tracks and being stealthy to ensure it is not seen. I mentioned the possibility of me purchasing a bike to parents a month or so ago as I began to work out what I wanted re transport going forward, and was told to expect to be booted out of home upon purchase. One of the two parents is known for knee-jerk reactions to a severe extent, so it will not be a pleasant experience no matter how it is presented. So I suppose I'm after some ideas and suggestions for how to go about this from those who either have been there before, or just have advice. In case it sounds like I'm irrationally worried, when I advised I was moving from university to full-time employment, I faced an entire hour of constant beration outlining the failure I was. Any advice, tips, etc, very welcome. Entire family will be present, along with best friend and partner. Would rather it not be a fireworks display.
