Im sorry that your fish died, its never easy to loose a pet.
I can understand that. Ive encountered people that
just dont want to or dont know how to let you in. I tend to wear my heart on my sleeve and can be a very open person. I have no problem doing things for people or expressing my 'like' for folks. Some people are too busy trying to look aloof and cool (most likely afraid of getting hurt) that they just can't go there with you.
I had to stop trying with some people. I feel like Im a good person and I think that its smart to hold on to good people because there are so many jerks out there.
What's funny about some of these folks is that when you stop trying, that is usually the moment in which they begin to reach out.... because they miss you.
Its kind of sad.
Some of my best friendships just fell into place so easily, that is how it should be.
