Having thought about the question while reading the answers here; I would have to say that THE most significant 'invention' has to be,  ANTIBIOTICS - something that is beneficial to all walks of life, both sexes, young and old etc. etc.

The Calyx is the roundy green part underneath a flower, like under a rose, the small cup like part with the little pointed parts sticking out from it. The word comes from another Chalice - or cup like.

Introvert -- to turn inward or in upon itself: as to concentrate or direct upon oneself. Basically if you are asking about a personality - it would be someone who is very shy and not talkative or chatty - quiet and reserved...

Extrovert -- basically the opposite of an Introvert -- someone who is very social and open, easily communicates,  a person who is unreserved.

The word or term "prolly" is not found in a dictionary - it is a slang word. You might say it is the lazy way to say or write the word "probably" - other than that I "dunno" LOL a little humor there eh?

If you mean the first three letters - how about Sumac ?

Frankly I think the best solution for your situation is to tell the parents that the next time there son refuses to wear his seat belt on your bus, will be the last time he will ride your bus. Period. Certainly you should be able to get backed up by your school administrator or employer -

If there should be, God forbid, an accident and the little stinker gets hurt because he isn't wearing his seatbelt, You and the school and possibly the department of education as well as the department of transportation involved in your town, city, county, state - will ALL be lined up for a high dollar attorney to hire to fight for their money, jobs and anything else in the lawsuit that the disgruntled parent will certainly slap on all involved!!! 

Put the little bugger OFF your bus - after you advise the parents that he is endangering the other children and you by not following the rules and disruption caused by you having to stop and pull over to re-belt their son back into the SAFETY of the SEAT BELT. 

INSIST the parent/parents come and pick him up from school BEFORE your time to take him back to where you picked him up in the day.  Best of luck to you. I wouldn't fool around with this, legally or otherwise, he could actually be the cause in a very negative future accident....

Anywhere between ten dollars and eighty dollars. Depending on which model of Blackberry you are using and the type of screen that requires replacing, here's a great site for you to check out if you'd like -- www.etech.com  best'o'luck, I know how awful it is when anything needs to be replaced or has been broken on your cellphone. 

Any wooden piece or item such as your cypress knee requires a lot of time. Depending on  how large your 'knee' is also is part of the equation - the bigger the piece the longer it will take. Your climate/temp will also play a part in the drying time - if you live in a climate with very high humidity - longer drying time, one that is desert like, less.  I know that large lumber yards, and timber manufacturers have special industrial kilns for drying the green lumber when it's cut --  I think you may be in for quite a wait actually. I know from personal experience, that even a green gourd requires an entire year to completely dry.  And they're hollow - so best'o'luck to you. I hope you have a great deal of patience.  I'd be interested to read what others may suggest also - one more thought, I wouldn't move it from where you lay it while drying either - as the moisture will shift from one side or end to the other - rather than letting it dry from the top down so to speak.  .  .
