Think about somebody you love. Somebody really close to you. Spouse, parent, child, friend.
Picture them dead. Gone. Away.
Feel the grief. Really feel it. Feel it till it hurts in your mind. Till imaginary tears are on the brink of becoming real.
Now realise that they are still with you. Today you still have them in your life. To be with and to love.
Kind of puts your stress about your crappy job, boss, financial situation, illness, traffic jam, delayed train, rude family member in perspective doesn’t it?
