I only have a very few 'Facebook friends'. I ignore most requests to be friends and have only ever had to unfriend someone - not because I didn't like her but because she tweeted absolutely every move she made and for some reason it all appeared on Facebook - her life filled pages and I couldn't sort the wood from the trees.
It is great to be able to see what DC and DGC are up to, especially since two DC are overseas and lead quite exciting lives! And I belong to a couple of closed or private groups from school and work which keep me up-to-date.
There is no need to accept a 'friend' request if you don't want to.
