I can make myself cry on command. All I have to do is think about how great dogs are and I get teary eyed.
Why does thinking of dogs get you teary eyed?
Because I love dogs so much. Just thinking about how much I love them allows me to get teary eyed.
I'm glad you are able to be very emotionally charged like this, you are very empathetic. You will be able to care for others very well, and without it you might not have very meaningful relationships.
I'm glad you can understand me. But this is making me think about dogs now.
I'm sorry I made you think about dogs just now. Your compassion is admirable and others will appreciate your caring attitude. Carry that with you and share it with others.
