triciaal · Answer

C is correct but do you understand why?

skullpatrol · Answer

More importantly, do you care?

dallaslifebaby01 · Answer

yes i do, Vijeya explains it to me

whpalmer4 · Answer

If you understand it, you shouldn't need to be asking Vijeya to answer it for you.

triciaal · Answer

not according to this thread

dallaslifebaby01 · Answer

well you can't see my private messages so you can't see her explanation

skullpatrol · Answer

Why don't you show us you truly understand and explain it now?

triciaal · Answer

well you don't need openstudy if you are studing privately

skullpatrol · Answer

vijeya3 · Answer

@triciaal there is something like 'pms' and something like 'vc'
I just don't understand why you can't help  a person in the way they want it?!
She doesn't need ur lectures -_-

dallaslifebaby01 · Answer

when i need a explanation i message her, if i need  more understanding i would rather do that in private then have the fact that some things i don't understand right away be in a public form and get judgy replies from people

triciaal · Answer

you are devaluing the learning process and wasting the time of others who are here to help those who want to learn

skullpatrol · Answer

vijeya3 · Answer

who asked ya to come here and interfere and then waste ur time? -_-

triciaal · Answer

what do you mean by "judgy replies" and from who?

skullpatrol · Answer

Live and Learn!

triciaal · Answer

@Vijeya3 Openstudy is not a private forum what about that don't you understand?

dallaslifebaby01 · Answer

I'm not wasting your time, you don't need to answer my questions I'm not forcing you that why i tag @Vijeya3 she understands my learning style and she helps me in a private message to wrk through it. y'all act like I'm not learning just because you don't see what has been talked about privately. If you can private message someone that is private, i asked the question in public and i asked @Vijeya3 for help, she works it out with me privately, a way i am comfortable with and thats not against the rules

skullpatrol · Answer

Let's ALL just move on to the next question please :-)

vijeya3 · Answer

I wish not to talk to you @triciaal just mind ur own business!
go and give her a useless explanation if ya want....^-^
