Crazy Fearless Tamed Wild Mouse | Is This Normal?

At first I thought this mouse has "Toxoplasma gondii parasite", but that is not true, 'couse it was scared in the beginning. Than it got braver and braver and we became best friends. I have really good memories how we played together many hours, many days. Unfortunately I had to take her away, 'couse she was getting under my feet all the time when I didn't see, and sooner or later I would accidentally kill her. So the only way to save her was to take her somewhere safe where she can be happy. I wish she could understand, forgive me and dosn't think I did it becouse I didn't like her. I miss her so much and hope I will always live in her memories, as she will live in mine. Maybe she misses me too and dosn't understand why I did that.
P.S. We have to face the truth - we will never see each other again, but at least you're safe.
Sincerely, your friend Eddy! :(
