A rare sighting!

My son does Food Tech at school and absolutely loves it - so when the governors were invited into school to see the students he volunteered to take part in the visit. My OH being a school governor was there too. They had a great day and piccies were taken, at which time OH spots Malachy washing up!!!! He asks Ms K to take a photo as this is behaviour we have never seen.
The teacher obliges, today OH was emailed the minutes from that meeting and one of the pics is Malachy hard at work...... however we still have not seen this behaviour replicated at home - oooh to dream!
