Marysol, your dress was so beautiful!
From watching the show, I really felt like you and Lea had a connection. I think Lea is just blunt nearly to a fault and sometimes she says things that she probably wouldn't have said had she thought about it more. However, I think her heart is in the right place and I think she cares about you deeply.
...Ana on the other hand, I don't think is someone to have as a close friend.
Sure, Lea has her faults, but she gives great advice and she has a positive outlook on life. Ana seems to have this absolutely rancid, bitter and nearly apathetic outlook on life. As you and your mother observe, energy is always important.
