I remember the first time I had soda. I was probably around five, and my older brother thought it would be funny to let me try a sip of Sprite, without warning me what it was. It HURT! All the bubbles fizzing and popping, it really hurt my tongue. But then, I have a sensory disorder, so I'm extra sensitive to light, sound, touch, etc. So maybe that's all it was. But in any case, I hated it. I can tolerate soda now, if I have to, although I prefer fountain soda to bottled or canned. It doesn't hurt as much and it seems to taste better. Usually, though, I can barely taste anything because of the bubbles.
