I remember in Pattaya a few years back... A friend had a long-term rental with him and one evening she had a bloodshot eye.
I told him then - "get rid of her, she's got something wrong with her".... she explained that they'd just got something in her eye at the salon to which I replied "get rid of her, she's got something wrong with her".
Anyway - no fucker listens to me, do they?
Next day her eye is red and puffy but nope - lover boy still won't trade her in for a new one.
Breakfast on day 3 & she's sporting double pink eye and my mate is sporting a single. Not once did I gloat and say "told you so"...
We went on a boat trip that day and in the evening we got back to a pub and she popped out to a pharmacy. When she came back she dropped the pharmacy bag into her handbag. About 15 mins later she popped off to the toilet, leaving her handbag behind.
Me being the consumate gentleman, I dived into her handbag, pulled out the pharmacy bag in which was a strange bottle with about 10 large red pills in it. On the side of the bottle, it said (and I kid you not) "for the treatment of ghonorrea and tuberculosis"
I passed it to my mate for a read, he looked at me and I at him and I said "Well, I haven't seen her coughing".
Back to England he ended up having 3 months of work with a form of virulent conjunctivitis the doctors had never seen before. Back in Thailand, for the next 6 months, every time I went to Pattaya it seemed like 25% of the girls AND punters had one or two pink eyes.
All those fluids passing between people - doesn't bear thinking about...
