Talks a lot and do nothing

How often do you come by with people that often talk a lot but do nothing? I am sure you have been through this before, what will you do with them? I just ignore them and I know the person will not keep quiet.
Nobody likes to be nagged and it is very uncomfortable. Even sometimes I feel myself nagging too much of my dear I will be bored.
I have dried hair at the end and every night I will put some hair cream at end to avoid them dry.
