Do you have any Contacts on you Phone that you don’t Utilize Anymore?

I just rewatched the episode where Robin keeps calling Don and how Marshall and Lily have phone numbers and contacts they want to keep. I think of how many useless contacts I have on my phone. People I’ve met and just don’t talk to anymore. Places I’ve been and will never go back to. I hold onto them for memory sake I guess. Do y’all have contacts or phone numbers that you hold onto?
