Context. From the book. La vida de Lazarillo de Tormes y de sus fortunas y adversidades (which I'm reading for pleasure). I'm having particular difficulties with this paragraph, and would appreciate some help.
Por el contrario, muchas tienen la costumbre de irse a refrescar en las mañanitas de verano, y almorzar sin llevar nada, con la confianza de que no faltará quien las invite.
My try:
On the contrary, many of them have the habit of going there in the early mornings during summer to take the air/refresh themselves, and to have lunch without taking anything (to eat), confident that someone won't fail to invite them (to eat/share their food)?
Thanks in advance.
