His difficulty was finding postage stamps for the self-addressed return envelope, and clearly the author is not American. Do you think it would be quite so easy to "buy envelopes and stamps" if you had to send a stamped return envelope to Nepal or Manila? Is that a "basic life skill" or would you have to do a little research to figure out what you'd need?
He had difficulty writing an address on an envelope.
This skill is something we expect of 8 year old children.
