The easy role can become difficult when it never allows a different mood.

Being the easy one is comfortable until the day you are not. The cheerful friend, the calm colleague, the one who never needs anything, all find that their role has no vacancy for a bad week, so a low mood arrives as a kind of contract breach and gets hidden rather than shown. The role was not imposed cruelly. It simply hardened, one pleasant interaction at a time, into something with no other setting.

Let one person see a different version of you this week without explaining or apologising for it. Roles loosen through small contradictions more reliably than through announcements.
