If playing makes you feel kind of silly, laugh! Laughter is relaxing and releases emotions; some therapists recommend thirty minutes of laughter a day as a remedy for stress. Humour, by putting things into another perspective, can smooth out moments of conflict and defuse tense situations.
While adults are worrying about the past and planning the future, children at play are absorbed in the present. They are more interested in looking at the rainbows in the oil slick on a puddle than in getting somewhere on time.
