Dither

I love this bike - I have an emotional attachment to it. But it's on eBay and I'm still dithering if I should sell or keep. But to be realistic, I'm 55 and was even too old for BMX when it first came to the fore. Riding this bike is the equivalent to me walking around with my trousers hanging round my arse. It's just not dignified. Someone has offered to swap it for a two year old Cube Acid. Is that some out of date medicine or another trouser faux pas?
