Over the years I have lost track of many friends, usually busy schedules don't help. But often distances and growing apart if what is important to them may not be to you. I do think if you have close friends and can connect on social media easily you really should make the effort, when I was more active on there I did. I since have given up traditional social media not wanting all my personal info being sold to the highest bidder.

Plus when I stopped working due to a health issue, you then find out who your real friends are. Disloyalty shows it's face quickly there, I understand what's you're saying 100%.
