Organizing Nuts and Screws

My husband always calls  his Dad every afternoon when he gets  home from work.   He feel bad that his Dad  no longer drives  which is  must be very hard for him.  He told my husband that he has been cleaning his garage and  organizing all the t-nuts and screws that he finds.  He said that my husband can take all of them and stock it in our garage just in case he need them.  He keep telling us that  he  feel like he won't be staying any longer,  which is very sad.  I hope it's not the case.
