I don't have any allergies at all, I always feels really bad for those who do though, some of my friends suffer from it really bad. We had to sleep in a tent on Duke of Edinburgh, but the field where we had to sleep was covered in crops and plants and things, so my friend's (even though she overdosed heavily on allergy tablets) eyes swelled terribly, she literally had slits for eyes. We helped her see the funny side, though, by calling her a mutant the whole night xD
