Why

 So why am I offering my paintings for you to buy at a price decided by you?

1. I need the space!!

2. Acuerdate de mi is a charity we may want to make use of in the future. 

3. I've had the pleasure of painting these pictures. Now is the time for someone else to have the pleasure of owning them. 

Don't feel embarrassed to offer whatever you wish. I won't be insulted!!
