It is advisable that one uses the Fevi Kwik Rs.5 pack judiciously. I will now qualify one such aspect of care.

It so happens that it comes with a cap for re-use. You use it once and put on the cap. A few days later, you pick it up again to glue something else. The cap opens, but the hole at the top is covered up with the hardened glue. There are umpteen options available to make it usable. 

It so happens, that I chose to open it, by biting on the hardened glue. Spurted out did the remaining glue into my mouth, causing my tongue to stick with itself in folds , my tongue to stick to the teeth of the lower jaw, my teeth of the upper jaw to stick with the teeth of the lower jaw and my teeth of the lower jaw to inner side of my right cheek inside the mouth. 

Instant panic allowed me to untwine my tongue and detach it from the teeth followed by separation of the now seemingly conjoined jaws and then the mouth. After a good 10 minutes of scratching my teeth and tongue with a screw driver, I had my mouth in a better shape than before and was able to talk. There is still some of it stuck to my premolars, but that is left to be fought with another day.

So now you know the moral of this story. 

And by the way, this is not the worst I have put my mouth to trouble. A couple of years back, I gargled and mouthwashed with Dettol. Strong after taste you know. May be you can try. So strong, for the next 3 months, I could not taste anything I ate. True Story, Akshay, True Story.
