Using windows to mac os

Can you guess what i feel in this image? Angry or confused? I am felt angry and confused because i am computer savvy of windows. I left my computer at our house and then i came here in the united states i started using my husband computer of apple mac (os) operating systems. The first time i used it i said why is so complicated this computer?! I just continue using it because i have no choice because i don't have my own.(LOL). Every time i want to use the right click of mouse because i want to copy and paste something it didn't work well though i highlighted the subject. So what i did i studied the shortcut key of keyboard and finally i got and learned. I have seen and read of one of blogger site and she said about on how to create or change the template of the blog and she mentioned about browser so i tried downloading a mozilla firefox browser . But i dont have a time to finish all her very interesting topic because of my little angel want's to occupy me. I used safari internet browser and i very notice the big difference of mozilla firefox from safari. Most specially when i check the blogger site. I really confused because i said why other bloggers can upload their pic and why i can't do.Every time i want to create or post a blog i didnt see any options or buttons to choose like font,numbers,dots,check spelling,upload pic,video and so forst before i used the mozilla.
