I love salt & vinegar crisps, but they always make my mouth blister. Never used to when I was younger; no idea why they do now, it's just one of those things I guess.
Yesterday afternoon, I succumbed, and ate a packet. Suffered for it for the rest of the day.
Was it worth it? I honestly don't know. But they were there, and I was hungry. Sometimes the little pleasures in life have to be worth a little suffering, I think.
