Yes. Generosity, kind words and helpfulness are all meaningful to the Buddha, however small.
From Vaccha Sutta:
"I tell you, Vaccha, even if a person throws the rinsings of a bowl or
a cup into a village pool or pond, thinking, 'May whatever animals
live here feed on this,' that would be a source of merit, to say
nothing of what is given to human beings. But I do say that what is
given to a virtuous person is of great fruit, and not so much what is
given to an unvirtuous person.
From Itivuttaka 26:
This was said by the Blessed One, said by the Arahant, so I have
heard: "If beings knew, as I know, the results of giving & sharing,
they would not eat without having given, nor would the stain of
selfishness overcome their minds. Even if it were their last bite,
their last mouthful, they would not eat without having shared, if
there were someone to receive their gift. But because beings do not
know, as I know, the results of giving & sharing, they eat without
having given. The stain of selfishness overcomes their minds."
From Sangaha Sutta:
"There are these four grounds for the bonds of fellowship. Which four?
Generosity, kind words, beneficial help, consistency. These are the
four grounds for the bonds of fellowship."
Generosity, kind words, beneficial help,
& consistency in the face of
events,
in line with what's appropriate
in each case.
These bonds of fellowship [function] in the world
like the linchpin in a moving cart.
From Sigalovada Sutta:
"Young man, be aware of these four good-hearted friends: the helper, the friend who endures in good times and bad, the mentor, and
the compassionate friend.
"The helper can be identified by four things: by protecting you when you are vulnerable, and likewise your wealth, being a refuge when
you are afraid, and in various tasks providing double what is
requested.
"The enduring friend can be identified by four things: by telling you secrets, guarding your own secrets closely, not abandoning you in
misfortune, and even dying for you.
"The mentor can be identified by four things: by restraining you from wrongdoing, guiding you towards good actions, telling you what
you ought to know, and showing you the path to heaven.
"The compassionate friend can be identified by four things: by not rejoicing in your misfortune, delighting in your good fortune,
preventing others from speaking ill of you, and encouraging others who
praise your good qualities."
From Dullabha Sutta:
"Monks, these two people are hard to find in the world. Which two? The
one who is first to do a kindness, and the one who is grateful for a
kindness done and feels obligated to repay it. These two people are
hard to find in the world."
