Hi Anyone wanna talk please

Sure, some people WANT to talk; but in some cases of injury, or birth defects causes them to not being able to talk AT ALL. So they have to write/type everything down to say something, or in some cases...people just want to be in solitude, weather they are depressed, or just wants some peace and quiet to clear their heads. some people don't want to talk to others because they are told not too, are shy, antisocial, bipolar(hate others and or self),getting bullied, doesn't trust others, or was even taught not to talk to others because there are severe consequences. But some people are just nervous, or have had so much trauma, that they have lost their sense of speech. but in my opinion, yes i'd love to talk with someone.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
