What does SRE stand for?
 
According to the following weblink there are 44 definitions.
http://www.acronymfinder.com/SRE.html
Not sure if I prefer Size Reduction Equipment or Snow Removal Equipment !
 
For those who show more interest in the sex and relationship education definition (note their singular relationship) it will come as no surprise to find that acronyms are very useful (particularly when space is at a premium) but can lead to mis/understanding/interpretation and the desire for change (which came first RSE or SRE?).
 
Having adapted/changed/unaltered many of the acronyms and words on our communications I have decided to use Healthy Relationships instead/as well but have yet to find a definitive acronym - any ideas?
