Can Vs Could 1

On my old Nokia phone in 1998, I _____ Skype.

I hope you enjoyed the party. I am sorry I ______.

I am very sad because I ______ on holiday this year because the weather is bad.

I am sick today, so I ______ to work.

When I was under 18, I ______ by beer in the bar.

I am free today, so we ______ the meeting.
