If he truly had post-nasal drip, it wouldn't be dripping from the tip of his nose, it would be stuck in the back of his sinuses liked a plugged up drain.   

You're not alone, however, with being uncomfortable with this situation.  I would have grossed out as well, and would not have necessarily had the courage to mention anything, or to simply walk away. 

Have you heard this one?  You probably have, it's been around for decades:

If you're out with your honey, and your nose gets runny, and you think it's funny, it's snot :) 

HAHAHAHAHA!! This was funny to me because I'm someone who hates snot/boogers/runny nose, you get the point. I've worked in the medical field for awhile now and can stomach most except that.  I would have offered a tissue or had to leave. My gag reflexes wouldn't have allowed for me to finish a conversation. Good job Gube!!

You've been getting pretty gross in your blogs lately, gube.  I admire that in a blog!

First anal leakage/drip, now nasal drip? HAHAHAH, what's next? You really make me laugh, enjoy your posts...

I had an elderly neighbor bring me a very big cinamon roll one time.  He had it in his hand and talked forever about something, I was focusing on the drip hanging from his beak.  Sure enough it drop and landed on my pastry.  I just said thank you, took it in the house and gave it to my grandkids.  Not really, I pitched it but it was a little gross.

A little off subject, but closely related. I LOVE those little taco's you get at those little family run mexican food places, in spite of what I've seen in the kitchens. Anyway, I stopped at one on Union Ave. a few years ago while I was working. I placed my order at about the same time that the cook came out of the restroom. The cashier told the cook, in Spanish, what to make. He walked right up to the food prep area and started making my tacos. I went to wash my hands and went into the bathroom which he had just walked out of. From the smell, he obviously had been eating to much chili verde lately. I turned on the water and then realized there was no soap in the bathroom. I stepped out and told the cashier I just got an emergency call and had to leave....

I have a three-year-old with a permamently runny nose.  Snot doesn't bother me, which is a good thing in my situation.  I have to use the nose bulb to suck out his snot, and it's stringy like mozzarella.  He wipes his nose all over the couches and his baby sister's stuffed rabbit.  He even comes up behind me and wipes his nose on the back of my shirt.  He's gross.

Catherine, it sounds like your son is destined to grow up to be a normal, fine young man.....

 EEEEEEEEEUUUUUUUWWWWWWW

I'm tellin' ya....we have nothing but class on these here blogs.  Some class and no class but class all the same.

There ain't nuthin' we don't talk about.

Thanks for the reassurance, OldBlue.  Sometimes I need it.  : )

SNOT! SNOT! -Frank Burns

Haven't we all at one time been in a situation of sneezing snot, passing gas, hiccupping, or some other unwelcome bodily function? If it's me, I simply say excuse me, be right back; retreat to the restroom or something and return to pick up where I left off. If it is someone else, I (try to) gently with understanding say, "Take care of that, I'll wait."
