Beautiful reflection Katyan. I do remember Big Blue Marble. My sister has a penpal experience similar to yours. We could only afford for one person in our house to have a penpal, because stamps we’re expensive. Relationships are beautiful and will always change and evolve. Taking the best from the experience is good, and learning from the rest is great 😊
Quite good heart you have as a friend. Sometimes though it’s not that someone does not wish to be in touch, it’s possible she can’t, and does not know how to keep the friendship door open.
