Ohh man. Pissed. Just what's apped a mate about his party that another mate reminded me of. Asked him about deposit, date, etc. Then my better half reminded me it's his surprise 40th. So I flapped and shot back onto what's app to delete the message but in the rush/panic chose the 'delete for me' option instead of the 'delete for everyone' option.
He hasn't been online since I sent it and people have been trying to get hold of his Mrs for me so she can get hold of his phone and delete but yeah, very uncomfortable right now.
