Time between birthdays

Today is the day between my father's birthday and my sister's birthday.

The small birthday party yesterday was lots of fun with some good chatting about many topics. There were issues about new jobs, cars, car engines, air filters for computers, computer networks, computer games, tenant rent discussions and some medical debates. This always happens when Prof starts talking, then few will get a word in. :)

For my sister I have had absolutely no idea what she wants or needs for her birthday.
