At work, I use Oracle Database - - I make some changes and if I don't like it, I just need to run the rollback command. However, in real life, no one can just simply rollback to the time in the past.
For me, my life continues moving forward. If I had tried hard being friend with someone and the person clearly did not want to be my friend, it's O-V-E-R...especially for someone who I had tried being friend over 1+ year until I couldn't take it anymore. WE ARE DONE! WE ARE NOT FRIENDS. WHY YOU ALL THE SUDDEN WANTS THE RELATIONSHIP BACK?! I want to spend time with people who has been there for me, who actually care about me, and who always respect me as a human being.
