Actually yes, one of them is having a cold (worse than mine) and one of the man I usually do RPG with has told us he is not sure if he will be able to come and play on Sunday as he is feeling poorly. He didn't specify if it is a cold or another thing, but I wouldn't be surprise.
I am feeling better, btw. And yes, tea with lemon and honey is something very common for sore throats here. I am not such a fan but it seems that it worked, so I am happy I did it.
